skiltz, Since this might be a new dump for MAME, I've let Smitdogg (The Dumping Union) know about this and forwarded your email to him to discuss about inclusion into MAME. MameTesters is geared more towards bugs in existing games than new dumps of games - so this isn't really a valid report. I'll acknowledge it for now to keep the lines of communications going. |

The speed listed on the chip isn't necessarily the speed it's being clocked at; they could be underclocking it because it's not necessary to run at it's full rated speed, or it could be overclocked (which I wouldn't be surprised to find on a bootleg board; they may get slower rated chips and run them faster, it's not like they particularly care about the quality of their product ;3 ) Only real confirmation would be to look at crystals on the board to determine the clock frequency, or (ideally) measure the clock going into the CPU. |

yep, what is said above, 8Mhz rated parts running at 10Mhz are common enough. Interesting bootleg, looks like it was made by Playmark (their stickers are on the roms) |

Hi! In DSC02796.JPG, look at the center under the Z80 CPU : XL2 -> 8Mhz. Near to the 68000 I've the XL3 20 Mhz? XL1 seem to be for the OKI cpu. In game I have a lot of slowdown, more than in the Tokib set in mame. If I've time for I will try to make a video... I have nothing to test 68000's speed... I'm looking for an oscilloscope ^^ |

Well for now can you submit the new dump so that it can be supported? the XLs are usually in close proximity to what they drive, so if the 20 is near the 68k chances are it's 20/2 and the z80 is 8/2 but if you say it has more slowdown there are other possibilities |

I've just redump wholes eproms... the 2 real differencies are on toki.e3 & toki.e5 all others are only filled with zeros (27C512 instead of 27C256?) You could find them here: goo.gl/ZhuzG |

I've also a lot of Gal 16v8 on board... I will try to finish my Gal programmer to dump them :) |

note, I've also set the 68k on the bootleg to 10mhz, slowdown might be closer to the board now |

Yes I've seen it, I will compare ASAP with the pcb :) |
