gameplaySP 0.5 beta released

[Robert]

GBA emulator for PSP

 

This is the first release.

 

gpSP mostly emulates the core Gameboy Advance system. As of right now it does not emulate any special hardware present on various GBA cartridges.

 

 

What it emulates:

 

GBA CPU: All ARM7TDMI ARM and Thumb mode opcodes except block memory w/ s-bit (probably aren't used in GBA games)

Video: Modes 0, 1, 2 almost completely, basic 3-5 support, sprites, windows/OBJ windows

Interrupts: HBlank, VBlank, all timers, all DMA channels, keypad

DMA: Immediate, HBlank, VBlank, sound timer triggered

Sound: Both DirectSound channels and all 4 GBC audio channels

Input: Basic GBA input delivered through PSP controls

Cartridges: Currently supports up to 16MB large ROMs (32MB will not load)

Backup: 32/64kb SRAM, 64kb flash, 512bit/8kb EEPROM

 

 

What it lacks:

 

Video: No mosaic, bitmap modes lack color effects (alpha, fades), there might be some minor inaccuracies in blending...

Cycle accuracy: Very cycle innacurate; CPU is effectively very overclocked, meaning games with rampant idle loops will probably run very poorly. DMA transfers effectively happen for free (0 cycle).

Please do NOT use gpSP as a first source for developing GBA homebrew, try No$GBA instead.

Backup: 128kb flash is not currently supported.
