notaz hat eine neue Version des Genesis/Megadrive Emulators für die PSP freigegeben mit diesen Neuerungen:
There seemed to be some demand for Sega CD/Mega CD emulator for PSP, so after doing the Gizmondo port I decided to port PicoDrive, my Genesis/MegaDrive/Sega CD/Mega CD emulator, to PSP.
Well I don't really like how it performs (it still needs a bit more work...
Zum Sega Mega Drive/Genesis Emulator hat eke-eke neue News in seinem blog veröffentlicht.
I decide recently to rewrite completely the EEPROM emulation code used in Genesis Plus. The previous one was based on Notaz’s Picodrive sourcecode but I was not really satisfied with it since it was not compatible with some games (Rings of Power, College Slam, Micromachines’ serie, …) and, beside from preventing game backup to work properly, also make some games crashing.
Since not so many Genesis games used serial EEPROM as backup RAM, this feature is generally not supported by the Genesis emulators out there (so far I know, only Kega, Picodrive and Jenesis support this, but none of them seem to have a full support).
The emulation itself is not very difficult since EEPROM datasheets (24Cxx eeprom are generally used) are freely available and the communication protocol is quite easy to reproduce. The main difficulty was to determine which games indeed use serial EEPROM (instead of classic parallel SRAM) and also which type of EEPROM it is and which type of EEPROM mapper they are using.
After testing many games on the emulator, I finally get some results and a list of games using EEPROM and their characteristic. I compiled this in a document, which emulators authors may find useful. In this document, there is also a quick note about EEPROM access protocols, which actually cover the three EEPROM’s modes found to be used. Interested people could also have a look at eeprom.c in the genesis plus SVN base.

GPFCE ist eine Portierung des NES Emulators FCE Ultra für den GP2x.
Finally it works the way I like, so here comes the release.
The goal for 0.4 version was to make the port full-featured, that is with all features of FCE Ultra intact (including compatibility), and to do it at sub-200MHz level. Well I don't think I really made it, but it should be pretty close.

Picodrive ist ein Genesis/Megadrive Emulator für den GP2x.Hier die Neuerungen:
So why to make PicoDrive, when we already have DrMd(x)?
* it can handle mid-frame palette changes, because it does 16bit rendering (water in Sonic).
* it can do shadow/hilight modes also because of 16bit rendering (check Skitchin' menus, Toy Story intro images, ...)
* it can emulate...
