My GCW0 is in the mail and I've been following this thread for quite some time now.
First thing Im getting on my GCW0 when it arrives!

HUGE kudos to you Nebuleon for all your hard work!

Awesome! Thanks a lot Nebuleon!

Awesome update!
I just renamed a few of my TempGBA's _0.rts files to .s00, .s01, .02 etc, and they work real good on reGBA.
Thanks Neb =D

That's weird.

On ReGBA/DSTwo, Doom has worked in every single version, even a freshly-made compilation of the very latest code. (albeit slowly)
On ReGBA/GCW0, Doom outputs garbled graphics in any version, including alpha 10. (and alpha 5 segfaults immediately)

I will need to investigate this.

Thank you nebuleon for you reply.In Doom 2 GBA version plays fine it doesnt have graphical errors,Doom GBA has graphical errors.Its the only rom i have this problem every rom i play its fine,maybe i have a bad rom from doom gba,anyways i will search for another backup.

Note:I installed the gba bios in their respective folder Regba

Edit:Video Example about the graphical errors in Doom GBA

<2 nested quotes omitted ~Nebuleon>

I would just like to compliment you for having one of the most detailed bug reports I've had for ReGBA. Not only does it contain an occurrence of the bug, it also contains your entire relevant settings and the ROM information. Bravo.

I get the same problem as you when trying it out on the GCW0, but it works fine on the DSTwo. I'll try disabling MIPS32 R2 instruction optimisations first, seeing as this is one of the big differences between the two ports.

Thank you jejeej

but the only merit its you nebuleon for making a good emulator for the GBA.If you dont have those options on the REGBA i cant detailed the bug report.I will try more roms if i see another bug i will post in this threads.Sorry for my bad english language its not my native language

ReGBA alpha 11 is available.

Download: https://dl.dropboxusercontent.com/u/106475413/gcw-zero/regba-alpha-11.opk

This build contains a quick fix for Doom's garbled graphics. As I suspected, MIPS32 R2 instructions are to blame. I disabled some of them (and will need to revalidate them before enabling them again later). The performance will be up to 4% less in any release from now on until the MIPS32 R2 instructions are validated, which will be unnoticeable in all games except Mario Golf and Tennis.

In this release, there is also a small change to the progress bar. The text is now inside the bar, and the background is TRS-80 blue.

The last commit that went into this build is commit fbc3d1a: "OpenDingux: Quick fix to disable most MIPS32 R2 instructions in the stub, but allow the SYNCI instruction.".

Nebuleon · « **Reply #129 on:** October 26, 2013, 05:37:07 pm »

I have revalidated the optimisations, and it turns out I used the wrong register in some GCW-specific code. I have fixed this, resulting in ReGBA/GCW0 alpha 12. Up to 4% of performance has been restored.

Download: https://dl.dropboxusercontent.com/u/106475413/gcw-zero/regba-alpha-12.opk

Dingoo A320 users don't need this; they can continue using alpha 10. Alphas 10, 11 and 12 will be byte-identical on the Dingoo A320.

The last commit that went into this build is commit dc526d2: "GCW Zero, mips/stub.S: Correct the MIPS32 R2 instructions. The instructions used the wrong register.".

Nebuleon, your dedication is admirable. Thank you!

What features are next for ReGBA? I would like to request a couple. Rumble and Tilt emulation. I have yet to utilize either of these functions of the GCW Zero, but aren't there a few GBA games that utilize them? I'd love to play them.

There are about 20 or so GB/GBC cartridges with a built-in rumble pack, but only 2 for GBA: Drill Dozer and WarioWare: Twisted!

Only 3 GBA games (and 1 GBC game) with tilt sensors:
Yoshi's Universal Gravitation (AKA Yoshi Topsy-Turvy)
WarioWare: Twisted!
Koro Koro Puzzle Happy Panechu!
Kirby Tilt 'n' Tumble (GBC)

Although it's only for a few games, having support for rumble and tilt would be big steps towards making ReGBA "complete" and "unique" for the GCW Zero.

Currently the firmware does not support force-feedback (that's like the last thing on the TO-DO list).

This is just a minor bug on Castlevania, not quite sure what you would call it. But I uploaded a video of it.

Yeah... This is a micro-bug I had only seen so far in Golden Sun battles - if you enter the psynergy menu or something, it shows 1 frame garbled. Perhaps the video-mode switching is at fault.

Thanks for the great (and fast) work on the emulator

I try it tonight ^^

I'm having problems with a lot of ROMs in alpha 12. Most of the mario games don't work. Mario Advance is all garbled, Mario Advance 3 won't load, neither will Mario Advance 4. Wolfenstein won't load

I tried the built-in gba bios, and the official nintendo one. Neither worked....

All 4 mario advance games and Wolfenstein work fine for me. Using alpha 12 with nintendo bios.
