|VBA for PSP|
|Version||0.03 (23 Jun 2005)|
VBA for PSP is the first Game Boy Advance emulator on the PSP made by 499.
Note: The last official release of VBA PSP is v0.03, which however is generally perceived as v0.04.
Make a folder on your memory stick called /PSP/GAME/vbapsp/.
Place the EBOOT.PBP file into the same folder.
Rename your rom file to rom.gba and copy it to the vbapsp folder.
Note: You can only store one rom at a time and cannot be over 16mb in size.
CPU clock can be set by default, you may find it slower than GBAPSP however.
R/L/Select/Start - Same as GBA
Circle - GBA A button
Cross - GBA B button
Analog Up/Down - Change CPU speed
Triangle - Increase frame skip value
Square - Decrease fram skip value
As with GBAPSP, it's a level of moving rather than playing, which is more suitable for games that will not be affected by the running speed, such as novel games.
- Pushing Right/Left on the Analogue stick turns sound on and off.
- Pushing Up/Down on the Analogue Stick turns the background from Black (222mhz), Blue (possibly 266mhz) to Red (333mhz). This give a noticeable speed difference on the Red Background.
- Pressing Triangle and Square increase or decrease frame Skipping.
