The homebrew technician, Ibicelyne, returns with an update for his FBA4PSP emulator application. This is a homebrew program that emulates MC680000/Z80-based arcade games so that we can enjoy them once again on the comfort of our very own PlayStation Portables. Here’s the changelog for the current version:

• Kov2p and kov2p205 are well supported.
• Kov2 etc. games state saving is supported
• You can configure screen size in ini file.
• A few other game drivers are added without test.

Here are the release notes from Ibicelyne for v12.4.0:

• martmast could not work due to arm emulation issue. Fixed in new driver. However, the new driver is too slow. So I didn’t include it into this build
• PGM game texture is incorrect somewhere.
• Olds100a can not work.

Thanks again to the developer for his diligent work on this project, and for making a bunch of great arcade titles playable on the small screen.

Fresh off the grindstone from underworld developer lbicelyne is FBA4PSP beta preV12p3, the newest iteration of his FinalBurn Alpha emulator. ARM7 is added in this release, and Knights of Valor 2 is also functioning fine this time around. Here’s a scribble from the developer himself:

• Game saving is not supported
• Usage:

1. It only supports kov2.zip and kov2106.zip
2. If there is sango2.rom in your zip file, please rename to kov2_v100_hongkong.asic

This is some terrific software, folks. Real keen code. If you don’t already cherish it, well, start cherishing it.

The mod created by Davex of notaz’s PicoDrive emulator Unofficial Picodrive was released today. Unofficial Picodrive 1.35b R (Rewind Mod) is listed as the final release. Nothing too huge in this latest drop, but a few adjustments have been made since the previous version. This much-hailed piece of homebrew is an emulator for the Sega Genesis and Sega CD game systems. Here’s the short changelog:

Now you can remap the rewind key (default RTRIGGER)
Allows you configure rewind parameters in the new “Rewind” menu, in order to have more rewind time or more smooth rewind.

Thanks to Davex for taking the initiative on the mod project, and thanks to notaz for the emulator’s core development. Another good collaboration from the PSP underground.
