| 詳 細 | Kazblox asked me to check the clocks on my Jumping PCB since the sound is slightly wrong. After doing so I found: 1) The crystals are wrong (or very likely multiple bootleg variants exist) - the 18.432mhz can also be a 16mhz, which makes little to no difference in-game 2) Above makes no difference because that's the CPU crystal, speeds should be as follows (assume for 16mhz fitted): 68k - 16/2 Z80 - 24/4 YM2203 - 24/8 (for reference) Y3014B - 1Mhz (driven by 2203s) Using the above clocks and dividers in a test build, MAME sounds correct. Not sure who is going to submit the actual fix. Side note will be dumping the variant I have since while very similar looking, the ROM layout is different - title screen matches jumpinga version. | ||||
