GBC boot code support

a GBC game on a GBA for instance doesn't dispaly the GBC bootrom [img]<fileStore.core_Emoticons>/emoticons/tongue.png[/img]/emoticons/tongue@2x.png 2x" width="20" height="20" />. Â Â Are you sure about that? The GBA contains the GB CPU & sound circuits, so why not?

GBC boot code support

OK, so I have the MFC settings already done.  Here's something very important by Costis Sideris: To my delight, the whole GBC boot ROM was sitting right there, mapped from 0×0000 to 0×00ff and from 0×0200 to 0×08ff ! External ROM is thus mapped from 0×0100 to 0×01ff and 0×0900 to 0×7fff. #...

GBC boot code support

Are you talking about me?

Â

What do I have to do to get these plaettes working? Just execute the BIOS right at the beginning and it will set them up correctly? That would be very easy.

VBA2 progress

Since only OpenGL is platform-independent, and is supported by Qt, I'd go with that.

During my semester break, I worked on VBA2. Â I now understand the ARM core reasonably and I started rewriting the complete graphical subsystem. Â I can already process VRAM data and the video registers to produce bitmaps of (character mode) BG layers. (See screenshot) Â Instead of rendering only...

dynamic recompiler to transform THUMB instructions to ARM instructions

Would it be possible to write a dynamic recompiler that translates from THUMB instructions to ARM instructions, so that existing instructions from the ARM core can be reused by the THUMB core? Would that give any benefits beside less code?

[Fixed]A Sound issue in M&L

@Squall: I think it can't be the hardware because gamerk2 writes that a certain GBA-sound channel is missing. Since VBA mixes all those channels into one single stereo signal for output, there's no way to hardware could leave that exact channel out. Â EDIT: I've tried it out and I have the same sou...

[Fixed]A Sound issue in M&L

It would be great if you could provide a save state where it happens and tell us what sound channel is missing. You can test that by manually enabling/disabling the sound channels in the menu.
