v0.2c 2002/01/13

gbongba-0.2c.gba is an attempt to add sound. In fact, it works great but at the emu speed ... slowly.
Thanks anyway to BeLogic for their great info on GBA Sound System. In fact, it's really like GB one.

The rom-select menu is pretty cool now. You can really scroll down, up. It displays info on selected rom. Try it with as many rom as you can. The limit is your gba FA cartridge size minus 323kbits and 128 games.

v0.2a 2002/01/05

Small fix for colors.
Messages: Only uncompressed roms can be appened to gbongba.gba, please (g)unzip them before.
Some GBC roms can work (eg. 001.gbc works). I have done nothing in that way. I can't/won't make a list of what is working or not, but do not hesitate to report to me if some rom should work, since I hacked a lot Virtual Game Boy v0.7.

v0.2 2002/01/03

Multi-ROM version, autoscan for roms and selection menu.
- Unix: cat gbongba-0.2.gba *.gb >> roms.gba
- Dos: copy /b gbongba-0.2.gba+rom1.gb+rom2.gb+...+romN.gb roms.gba
- (please respect blanks, otherwise ask in gbaemu forums)
The limit is: max 128 roms and max 32 MB, but since the menu is crappy, it will only display 25 lines and will overlap badly if exceeded. Expect something much better soon.

First stand alone version of gbongba. Usage:
- Unix: cat gbongba.gba rom.gb >> rom.gba
- Dos: copy /b gbongba.gba+rom.gb rom.gba
News about assembly : all things I rewrote in asm seem slower that those produced by gcc. I tried Jeff's fast thumb or arm DrawPixel, fast arm/thumb mem access, without any mul or excessive ld usage, it's still slower than c. Still working though.
