Finishing HLE - Help needed

[olivieryuyu]

Hi Guys!

I am about to quench all HLE known bugs. Is there any bug which you may be aware of?

For that you need to compare HLE and LLE with GlideN64 and see if there is difference.

HVQM and SDEX issues does not need to be reported.

If nothing comes up, I will stop my work on HLE deciphering. So please help to find any remaining bugs!

See ya!

[oddMLan]

I've noticed this for a while, but thought it was really minor so I didn't report it.

HLE

LLE

LLE has dimmer (and much more accurate) lightning.

[olivieryuyu]

Ok CBFD looks a candidate for decoding.

[ShareScene]

maybe this? #1509

[loganmc10]

Reported from someone on Reddit:

Turok 64, the sun has no lens flare with GlideN64 but does when using angrylion rdp plus.

[olivieryuyu]

where are the lens flare?

Is it the same in LLE with GlideN64?

[olivieryuyu]

maybe this? #1509

Nope

1731 Is this a possible candidate?

[Kidboy17]

Here is one for HLE only, #1912

Another one, #1736

Nope it is the same in LLE.

OK, weird one...

[olivieryuyu]

Nope

and... what about Resident Evil 2 ucode? is it completely deciphered?

[loganmc10]

and... what about Resident Evil 2 ucode? is it completely deciphered?

Yes I believe so, works fully in HLE (https://gliden64.blogspot.com/2017/04/resident-evil-2.html)

[fbeuter]

RE2 works properly now, but if I'm not mistaken, it's still using the same hack from Glide64 to display the backgrounds correctly. The correct behaviour has never been fully deciphered.

[loganmc10]

Perhaps, but either way that is not a ucode issue (HLE vs LLE)

[Tasosgemah]

nvm, Goemon's Great Adventure seems fine.

[oddMLan]

Guys, olivieryuyu is asking only about issues where HLE looks different/incorrect than LLE mode.

[LegendOfDragoon]

@olivieryuyu would you be interested in HLEing GB Tower in pokemon stadium 2?

[olivieryuyu]

@LegendOfDragoon

if we do speak of a a gfx microcode to implement, I am fine with that. Please give savestate for this for PJ64.

[olivieryuyu]

Cannot find the bug. Need PJ64 savestate.

[LegendOfDragoon]

Technically the task type = 2, but it certainly deals with graphics. It may be like WDC where it deals with both audio and graphics in same task. I tried making a savestate, but it doesn't work. I believe PJ64 has a problem with savestates when using transfer pack in-game.

[olivieryuyu]

@LegendOfDragoon

Just provide a savestate before getting into the screen where the ucode starts.

[LegendOfDragoon]

@olivieryuyu PJ64 seems to clear the transfer pack data when loading a save state. I guess you can hold off on it until this issue is fixed. I may look into fixing it next weekend. I even made a savestate at the game pack check screen and there's no game pack when loading the save state.

Found where it is but it works in LLE and HLE without any issue.

[olivieryuyu]

Holy Moly, Conker lighting is quite something. There is not one but actually two lighting modes!

[Frank-74]

There's still Stunt Racer 64 and World Driver Championship to be HLE'd... Only then can Finishing HLE be possible...

[loganmc10]

@Frank-74 that is already done

[Frank-74]

@loganmc10 Has it? I still get RunRSP error on booting WDC with HLE Gfx in Project64. Using latest WIP GLideN64.

[ShareScene]

it was implemented long time ago by Gillou68310

[ShareScene]

https://github.com/gonetz/GLideN64/pull/1717

[Frank-74]

Well, WDC LLE Gfx boots fine with latest GLideN64 WIP. Choosing HLE Gfx results in RunRSP error. How do I get it to run HLE gfx with Project64?

[LegendOfDragoon]

@Frank-74 i think it only works in mupen64plus.

[theboy181]

At this point mupen is the emulator of the future. They have been adding hacks to get their games running so that development for GLideN64 can continue. At the time this game was added to their comparability list more contributions were added to the puzzle from their developers.

[loganmc10]

It wasn't any kind of hack that allowed World Driver Championship to work with HLE, we extended the gfx_info API to include SP_STATUS_REG, that is what was needed for WDC and Stunt Racer:

https://github.com/mupen64plus/mupen64plus-core/pull/423

If PJ64 did something similar then those games would work in HLE

[theboy181]

I’m sorry. I did t realize that that’s how the real hw worked. What about gauntlet then? Hack?

[loganmc10]

Gauntlet Legends was a similar situation, the GFX plugin needs to be able to modify the SP_STATUS bit.

It's not really a matter of hack/no hack. Because of the plugin system, the GFX plugin didn't have the ability to modify all of the RSP registers, it was a shortcoming of the original API design many years ago

[olivieryuyu]

Guys, this is getting off topic. Can you please provide HLE bugs? Conker deciphering is already started. Mario Party should next. Anything else?

[schubertguilherme]

Hello, olivieryuyu, slowdown game Mortal Kombat Trilogy in stage "The Subway" and bug graphics in Top Gear Hyper Bike "textures". Fix please. Hugs and sucess.

[olivieryuyu]

Nothing to do with HLE.

[theboy181]

The stage in hyper bike? What is the issue then?

[Frank-74]

Top Gear Hyper Bike is same bug with ground textures in LLE and HLE with GLideN64. But Angrylion gets it right.

[olivieryuyu]

Conker nearly over. Anything else?

[StenApp]

Is there a list of non HLE related errors? I lost the overview of what is what type of problem

[olivieryuyu]

Nothing else ?

[ShareScene]

I think u should take a look Resinde Evil 2, because ucode is not totally deciphered... instead of that is totally hacked.

[olivieryuyu]

There is no ucode issue with RE2.

[GamingTVYT]

@schubertguilherme What is the WIP you are using, please? I'm going to test here to see if the same error occurs.

[olivieryuyu]

Again this has nothing to be with HLE. Please stop using this issue for non HLE issue!

[Kidboy17]

Issue #1484 ? Even though it uses per pixel lighting, the issue is only in HLE mode.

Issue #1803 which leads to issue #1647 ?
