Reicast get Dolphin Blue to work ?

[ghost]

Step 1: Describe your setup:

• hakchi2 CE version: 3.4.1
• retroarch used (filename): KMFDManic-NESC-SNESC-Cores.9-3-18
• hmod(s) used by the game you are having problens with (filenames): KMFDManic-NESC-SNESC-Cores.9-3-18

Step 2: Describe the problem:

Hi mate, ive watched your video about Atomiswave (great job again by the way). I didn´t got blue dolphin wo work so far. ive placed the bios files correctly (as far i can tell). ive tried to add dolphin.zip and the extracted .bin file and start it with /bin/reicast parameter but it just get black screen and fall back to snes menue... youve talked alot of .gdi , .chd files but i guess thats just for dreamcast not for atomiswave. so first question is which roms do exactly work for atomiswave they are not quite common ;-) and second how to add exactly... extracted, .zip or do i need to convert them anyhow?

the dolphin.zip i have has a .bin and some .icx files inside... guess wrong rom??

if i add the game, reicast emulator is not shown on the available list. so guess it need to be implemented either.

cheers

//Edit: ive found rom with .bin file format, but also not working... situation is unlclear for me what to do , to get it run ?

//Edit 2: ive tested my roms with NullDC r150

Demolish Fist (working)
Dolphin Blue (working)
King of Fighters NeoWave (working)
Metal Slug 6 (working)

Checksum check byte filesize to hexcode for .lst https://www.binaryhexconverter.com/decimal-to-hex-converter

4 everyone lookin for the correct bios files, this might help (md5 checksums) ;-) https://github.com/libretro/libretro-super/blob/master/dist/info/reicast_libretro.info

Reicast is showing me now all Bios "Firmware" files are present, i made sure the md5 hash is correct... i really dont know at the moment where the issue is.... i saw you captured the video through retroarch 1.7.3 , maybe its not working with 1.7.4 ??

ive tested ikaruga with .chd format, working but very slow. so i think core is setup correctly at least for DreamCast itself.

my dolphinblue.bin md5 hash is; 761737ab98bde7e7883efe5df5e2133f https://md5file.com/calculator (you need to checkmark the checkbox for md5, deselected for default)

[ghost]

I solved it myself, man pal, what a mess, you could have spared me hours of searching, why that does not work, this odyssey of mine can help anyone try out this stuff "What can you do wrong?" ^^

so the default recommendet bios is not working (hash) instead i found one which worked on pc and snes mini ! Filename: epr-21579d.ic27 with MD5 765bc6e3366d3d63593a59febb4acc53.

1. make sure you have the correct bios files (can check on the supplied md5 hashes).
2. make sure you reset your snes mini if already installed with bios hmod (its not overwriting the existing data)
3. make sure you use kmfds supplied package from 18-09-03 or newer for retroarch 1.7.4 or newer
4. make sure you have converted atomiswave/naomi games which work also for NullDC Naomi on PC (you can check on your pc first) if the game does not run on pc, you dont need to trie on snes mini.
5. make sure you have a .lst file for your rom. if not create one. use the file size in bytes and the https://www.binaryhexconverter.com/decimal-to-hex-converter to get the correct hexvalue.
6. MD5 values for at least my working set is:
   • naomi_boot.bin | 765bc6e3366d3d63593a59febb4acc53
   • dc_boot.bin | e10c53c2f8b90bab96ead2d368858623
   • dc_flash.bin | 0a93f7940c455905bea6e392dfde92a4

The sound really drives me crazy with this stuttering ... hope you find a way to optimize the performance for us fingers-cross

Sorry, I was working, and didn't have a chance to help out or respond, as of yet. I would have been able to sort your issue out very fast! I appreciate the compatibility tests on the Atomiswave Games! Props to you for your thoroughness! Rumblefish Games working is a good thing, as they had issues in the past. Demolish Fist, despite working, might not have "controls". Note, some of these games may not have controls, whatsoever.

For the record, the BIOS should overwrite existing data, if using /hakchi/transfer If on Hakchi 3.4.1, you'd need to uninstall/reinstall, since it would register as already installed. And, yes, some hash checksums that are recommended, are not always the ones that work out best, unfortunately!

Ikaruga, unfortunately, will likely remain slow. But, Many Many other games run a steady and very solid 30 FPS with the Performance Upgrades I have done! Be sure to check out Drill, Hydro Thunder, Marvel Vs Capcom 2! And, you are always welcome to email me! I am very glad you put in this effort, as your test results are great! We just need to confirm which games do or do not have controls properly hooked up! You rock, as always @AntiFly Welcome to the wonderful world of testing, testing, testing:) Never forget my email is always there for you, anytime! I work a few double shifts throughout the week, so there are lull periods where I cannot properly respond for at least 10-14 hours at a time! Keep in touch, man! I will leave this Issue Open, for now, so we can address compatibility/control concerns! I will post this compatibility for the Next Update. And, of course, I will shout out to you for your hours of testing! That is very much greatly appreciated, without a doubt!

So, last note, I will add a Compatibility File for Next Update, it will cover Naomi/Atomiswave/Dreamcast Games!

Hope you are enjoying the Update/Core, as well as the ability to run Cores with far less NAND Space being used, my friend:)!

[KMFDManic]

One more note, my friend, I will very much emphasize this with every Update...But, after installing Cores, BIOS, etc, it is very important to install RetroArch 1.7.4, by itself, after those. Reason why? Well, if you install RetroArch 1.7.4, then certain Cores, their defaults will conflict with RetroArch Set-Up, and can slow some games/cores down. But, installing after, no issues, whatsoever, as RetroArch will reinstate the proper values for said cores/games:) Again, thank you for your effort and time put into this endeavor!

[KMFDManic]

@AntiFly Justme488 has started taking information from me, to help make necessary BIOS, etc, more convenient and easy to swallow. Check out Xtras/BIOS, and the Advanced BIOS.pdf. I think we can utilize that pdf to put in all the detailed BIOS Checksums necessary! If you'd like, you can email me, and I will give you details on how we can pull that off. The officially accepted ones, as we already established, will not always be the best way to go. But, we can prioritize this, as I know this is something very irritating for you and many others! I will even include the md5 tool, which I have used hundreds upon hundreds of times over the years! I will be doing another double shift tonight. But, this will be the next agenda, if that suits you! I always welcome your feedback and adjustments that benefit the Core Set for the better!

[ghost]

@KMFDManic thanks for your input mate. the information about the order on installing cores in special retroarch is a essential one. if i remember right such information already exist for the ppssp core but i thought from the logicall thinking it would make sense, retro arch as a core and the others as "plugins" as you may say so.... i created this list for myself to remember the order. _INSTALLED_MODULES.txt

I now will change the order of retroarch to the end of my install process, that would be your idea right?

Your idea to put the MD5 sums into the bios pdf is great for everyone.. lets do so !

cheers :+1:

[KMFDManic]

And, @AntiFly , if you got to see the first Dreamcast Release, and, even the 2nd...The 3rd one (current), is far better! I am very happy to be able to play dozens upon dozens of games fully, at 30 FPS! We are working on finalizing the BIOS Guide, and you will have a testing credit in it, per my request. If you do not mind, send me an email. I would like to do compatibility comparisons with the Naomi Boot I am using, versus the one you are using. Otherwise, all is excellent on my end, and ALL BIOS are covered and accounted for. I just want to reaffirm which md5 I will go with for Naomi. This will definitely go into next Update:) We currently have only 3 Cores that are not yet functional (no success loading games). These are Hatari, ScummVM, and Free2JME. I will make sure these are notated, so people don't go crazy trying to run them. They are there, just like I originally posted P-UAE, in case! Amiga will certainly get better, as well! Keep in touch! I will look for your email, and this Guide will be completed over the weekend. I will email you it back in a response so you can give your input.

@KMFDManic , I have some cores in use, you could see on my _INSTALLED_Modules.txt, so yeh I could double check some of them, no problem ;) Unfortunally I dont have your e-mail , we correspondended just for the github mail. I suggest you got this as me in CC. So if you like correspondend to an old thread and we can exchange for that behavior ;)

I currently review the roms ive got for Atomiswave, Naomi, Chihiro and Triforce,... remove dupes, create .lst and repack with 7z. ("for testing purposes")

ScummVM runs on my X360 fine, could give this a double check on snes mini in time... I run the amiga, commodore etc.. consoles on my X360, i really dont want to check them on snes again, thats a nightmare getting these to run.

//Edit, there is definitly a issue while installing different cores now. i put all of my cores into + cheat plugins and CPS1 games wont work then, even reicast wont work at all... I ran 1941 on fba2016 latelay, wont start at all now. I reinstalled retroarch again but didnt had any positive effect.

changed order to this: 2018-09-07

_km_ppsspp_neo _km_pcsx_rearmed_neon _km_Zram_Crash_Inhibitor -install hmods after each other to this point: km_2048 (exit psp games) _km_BSNES _km_fbalpha2012 CPS2 _km_fbalpha2016 _km_gambatte _km_genesis_plus_gx _km_mame2003_xtreme _km_mednafen_pce_fast _km_mednafen_wswan _km_mgba _km_mupen64plus _km_parallel_n64 _km_picodrive _km_reicast _km_snes9x2005 _km_snes9x2016

--USB-HOST-- MM C8 Error Dterrent

--LAST-- -install hmods after each other: _km_retroarch_174_xtreme _km_master_bios_module _Hackchi advanced_music_hack.hmod _km_retroarch_custom_borders _km_retroarch_xtreme_ppsspp_add-on _km_retroarch_xtreme_shaders_add-on _km_retroarch_xtreme_database_add-on

cps1 is now working again, but reicast wont work at all! core can be loaded but no game can be boot.

// at the moment reicast just working if i install it "standalone"

1. retroarch
2. reicast + fba2016
3. bios modules ive load a fba2016 game to get into retroarch

[KMFDManic]

@AntiFly You really shouldn't be having conflicts like that. Are you trying to run these via NAND or External RetroArch? It very much seems like you've maxed out your NAND by installing the database, which takes up a lot of space. If you are breaking a Core, then installing another, and breaking another, that simply means you are using far too much NAND. Custom Borders also takes up a lot of space. So, essentially, from the get go...

Hakchi 3.4.1, Reset Kernel OR Uninstall Kernel, then Install/Repair Kernel

Then, install Master BIOS Module, along with primary Cores you want, such as Reicast, etc. Be careful with Custom Borders and Database, since they are BIG HMODS! Then, after these are installed, install RetroArch 1.7.4 Xtreme, by itself:)

Keep me posted!

[KMFDManic]

@AntiFly Here is a little trick that may make things easier. If you use hakchi/transfer and install an HMOD, that should Update, and you do not get a Double Splash Screen, it generally means system wasn't properly shut down, and/or flash drive/hard drive may need checked for errors. I occasionally have this happen due to not safely removing hardware! But, if you see hakchi logo twice, it usually means the hmods have installed:)

[ghost]

@KMFDManic Ive tested some of my favorite games with the "recommended" bios. So at least one of the error02 games from my former test was working, but its obsolete for me "Capcom_vs_SNK_Millenium_Fight_2000_Pro".

Since the games im intrested in are working both the same I will stick with the bios ive discoverd working.

// km_retroarch_custom_borders_9_3_18.hmod + RetroArch Xtreme Database Add blew up my nand. these things are really huge with 79MB. You may implement a warning in the Maintext for the HMOD. In particular a size value would be great for every hmod somewhere in the headline :)

//my former test with that bios was just a bad one cause I guess youre right the nand was full. that drove me to look for a bios alternative which wasn´t really a need for, but fit in the end for me well.

[caretakerz]

Ok, so I found a bios with the same checksum. Renamed it to naomi_boot.bin. Placed it in the dc folder in master bios module. Uninstalled everything, including kernel, and reinstalled them individually, with _km_retroarch_174_xtreme_9_3_18.hmod being last. Checked rom file with .lst file, and they match. Everything seems to be in order, but my game still won't boot at all. It just kicks me back to the menu. What am I doing wrong? Is there a change in the command line that's necessary? Should it be directed at the .bin file or .lst file? I've tried both, but still......nothing.

[KMFDManic]

@caretakerz Make sure the lst file is NOT compressed. And, also simplify the names of the bin or dat, then modify the lst to account for that. I have dolphinblue.bin and dolphinblue.lst Obviously, the name of the lst file won't matter, since it is essentially just a cue! But, simplify the bin or dat, then modify the lst file to have exact same name, using notepad++ I have it in Xtras/Tools

[caretakerz]

I'll try that. What about the command line? Should it be /bin/reicast /var/games/CLV-I-FVBIO/dolphinblue.bin, or /bin/reicast /var/games/CLV-I-FVBIO/dolphinblue.lst?

[caretakerz]

HAAAAAAALELUJAAAAAAAAAHHHHH!!! Finally got it! MVC2 is very slow, though. Simplifying the name of the files did the trick. Going to try the games that are running better. Thanks

[KMFDManic]

@caretakerz Dreamcast Version of Marvel Vs Capcom 2 runs fine:)
