- Adds support for TMS9918-based display modes, making games like F16 Fighting Falcon and Rozetta no Shouzou playable
- Saving changes to controls is now automatic (no longer need to press X to save)
Unzip smsppsp.zip into /PSP/GAME/ folder on the memory stick.
Game ROM’s can reside anywhere (the ROMS subdirectory is recommended, but not necessary). SMS+ PSP can load ROM’s from ZIP files.
Starting with version 1.2.55, SMS Plus PSP includes a “time rewind” feature, which allows you to rewind recent gameplay (approximately 20 seconds). Map ‘Special: Rewind’ to any PSP button to enable this feature.
During emulation:
| PSP controls | Emulated controls |
|---|---|
| Analog stick up/down/left/right | D-pad up/down/left/right |
| D-pad up/down/left/right | D-pad up/down/left/right |
| [ ] (square) | Button 2 |
| X (cross) | Button 1 |
| [L] + [R] | Return to the emulator menu |
| Start | Pause/Start |
By default, button configuration changes are not retained after button mapping is modified. To save changes, press X (cross) after desired mapping is configured. To load the default mapping press ^ (triangle).
To compile, ensure that zlib and libpng are installed, and run make:
make -f Makefile.psp
- Time Rewind feature by DaveX – “rewind” recent gameplay (approximately 20 seconds). Map ‘Special: Rewind’ to any PSP button to enable this feature
- When switching games, latest save state will be automatically highlighted
- Rapid fire support – map any button to A or B autofire (‘Controls’ tab). Change the rate of autofire in the ‘Options’ tab
- Snapshots are now saved to PSP’s PHOTO directory (
/PSP/PHOTO), and can be viewed in PSP’s image viewer - File selector snapshots – while browsing for games with the file selector, pause momentarily to display the first snapshot for the game
- Added animations to the menu UI
- Fixed buffer overflow error affecting units without a battery
- 20% speedup in emulation speed with new 8-bit video rendering
- Option to turn off FM emulation for an additional 48% improvement in emulation speed. This means that with FM emulation disabled, all games will play at 100% speed with VSync enabled
- Various small bug fixes
- Fixed a bug that caused subsequently loaded games to crash
- Added an option to use a faster, less accurate sound emulation engine (improves performance by 3-4 fps)
- Added an option to remove the leftmost vertical column for SMS games
