Some patched games doesn't work #283

Open ghost opened 6 years ago

ghost commented 6 years ago

I'm using a fan translation (https://www.sadnescity.it/traduzioni/ff7/ff7_psx.php) of Final Fantasy VII PAL. The the game loads but it's just a black screen with the title menu theme. The files are in bin/cue (checked md5/sha-1 on redump org and they are fine, FF7 didn't had any .sbi files for PAL), BIOS are present and MD5 matches correctly. Checked ECC with ECCRegen and it's good.

I've tried to change the video driver (gl, software, vulkan) but nothing have changed. Other cores like PCSXReARMed and ePSXe standalone loads the game correctly and without any issuse.

But It's the ONLY game I have that act like this. I'm also using a fan translation of Chron Cross and it works without any issue

When you checked with ECC regen, fixed some errors or was NO errors at all? You tried generate your own cue file after the check? (I use imgburn for that). Also, check in the patch website for the emulator compatibility.

The website doesn't mention any emulator comaptibility (It works on real hardware and ePSXe) ECCRegen reported no error. I have scanned every disc multiple times and no error

I'm using the "official" .cue from redump org and this is what's inside:

FILE "Final Fantasy VII (E) (Disc 1) [SCES-00867].bin" BINARY TRACK 01 MODE2/2352 INDEX 01 00:00:00

(obviously the file name inside/of the cue matches the .bin)

I remember, a problem with the Psx Doom game. The oficial (redump) cue file dont work, some user here give me the correct text for the cue file. Maybe the redump format is not perfect.

I recommend generate a new cue file after patching your game. But i use the "beacause" retranslation of FF7 without problems. In fact, i use many translations, and aside from using ecc regen and create a new cue file, i not have any problems.

You can try burning them and re-dumping them again if you have some spare blank CD's around. The CD drive firmwares will invisibly fix some inconsistencies as the image is being burned to disc, and it might catch something ECC Regen missed. This could explain why it works on hardware too.
