Thanks to e-lation for the news.

08-04-2006 - JAPE

Lots of good news regarding JAPE 0.10...

By the way, starting from now, I will only list most important changes and not reuse the long update list from MAME.

 

Here are latest news:

 

* New M6502 CPU emulation support (seems to work nicely).

* Added fully-working support for Bomb Jack, Congo Bongo, Centipede, Nibbler.

* Incorporated most changes up to MAME 0.10.

* F10 to toggle speed throttling, F11 to toggle FPS display.

* Added character buffer emulation to facilitate C porting to Java.

* Added a C++ preprocessor in the compilation build to enable the use of macros in Java (yes, there are many macros in MAME).

Slot/fruit/poker machine emulator (depending where you live).

AGEMAME (formerly MAGE)

 

0.35

 

Included all updates from 0.106 to 0.107

 

AWPSim again revised, into AWPVideo - a series of functions that any driver can access, to  provide a unifrom platform for future simulator development. The original system has now been totally disabled, but as of writing there is no sample simulator layout available (lamping is improving, though).

 

The system still isn't perfect (Ideally, different video components should be placed on different 'screens', but that will require a rewrite of the AWPVid external components (vacfdisp, bfm_dm01 etc).

 

AGEMAME is still using a different MPU4 core to regular MAME, while I try to work out some communications issues - when ready, I'll merge it back in.
