Racing Jam (JAC)
This racing game boasts (at least) 24 cars and 4 different modes of play, with differing difficulty levels : Time Trial and Circuit Course racing (beginners and intermediate), uphill and downhill versions of Winding Road (expert), and several Gymkhana Racing modes. Like "Gran Turismo", it is possible to upgrade engine power and suspension.

WIP:
- 1st September 2012: Ville Linde - I've been trying to figure out what is causing Racing Jam to crash. Turns out a display list function on the SHARC ends up overwriting the display list and wreaking havoc. I'm still not quite sure why this happens, as the Racing Jam DSP microcode is very similar to Gradius 4, which works just fine. I managed to hack things a little bit to get past those problems, and the game eventually boots up, but quickly dies to a network error. Pretty much as expected. I also managed to figure out the "-11N" error in Racing Jam 2, which turned out to be a LAN board EEPROM (or serial number chip) test. RJ2 has identical SHARC problems as RJ.
- 0.142u1: RetroRepair added clone 'Racing Jam: Chapter 2 (EAE)'. Changed parent description to 'Racing Jam (JAC)' and clone to 'Racing Jam: Chapter 2 (JAE)'.
- 0.135u4: Fabio Priuli moved K056800 sound device to emu\sound and removed the old code. Updated Racing Jam to use this implementation.
- 0.133u3: Changed RF5C400 sound clock speed to 16934400 Hz.
- 0.127u2: Added M48T58Y RTC/NVRAM timekeeper rom to 'Racing Jam' and clone 'Racing Jam: Chapter 2'.
- 0.114u2: Added Stick, Paddle and Pedal control.
- 0.114u1: Added 'Disable Machine Init' dipswitch. Removed 2nd Player.
- 5th April 2007: Ville Linde - Racing Jam and Hang Pilot are finally starting to show something. I had to force the SHARC not to execute the display list because of some weird bugs, so no 3D graphics yet.
- 0.110u3: Added RF5C400 stereo sound.
- 0.97u2: Changed user3 roms ($800000 + c00000) to user5.
- 0.97u1: Added 68000 (16MHz) CPU2 and ADSP21062 (36MHz) CPU3. Swapped user2 roms. Added dipswitches 'Test Mode' and 'DIP2-DIP8'.
- 5th June 2005: Ville Linde - I decided to have a look at what's wrong with Racing Jam: Chapter 2 as it was the last of the Konami PowerPC games not to boot yet. There was a small problem related to ROM loading, and now the game boots just fine. The test mode hangs on network board test (not emulated yet). Without running test mode, the game starts to boot normally (with the fixed backup RAM), but ends just spinning there, without showing anything. Turns out that Konami Hornet and NWK-TR games require some preformatted data in their backup RAMs (probably as a protective measure). So far I've managed to find the correct values for Gradius 4, Silent Scope, Racing Jam and Racing Jam 2, leaving Silent Scope 2 and Thrill Drive to be done. Silent Scope and Racing Jam start to boot but end up spinning much like Racing Jam 2.
- 0.86: Ville Linde added Racing Jam (Konami 1998) and clone 'Racing Jam: Chapter 2' (Konami 1999) and various other Konami PPC based games: GTI Club, Gradius 4, Silent Scope, Silent Scope 2, Thrill Drive, Midnight Run and Winding Heat. These are to demonstrate the PPC core in action, they contain only very preliminary emulation and do nothing more than display the initial test screens.
- 11th July 2004: Ville Linde - Hornet games hit a deadend, so I quickly moved on to NWK-TR games with some success. Racing Jam and Thrill Drive hang to some IC tests, much like the Hornet games.
