I honestly didn't know what I was talking about when I first mentioned VROMs but I decided to take a second look (was in a bit of a rush last morning). IC1-16 are all the banked CROMs (according to Supermodel) and have the correct load locations. lemans24 has the same exact memory test as lostwsga and marks the exact same CROMs as bad too. |

Confirmed. lemans24 doesn't have IC13/14/15/16 in its memory test. |

By the way, Ocean Hunter internal memory test marks as bad for this time already all VROMs and IC17 and 18 EPROMs, althought most CROMs are "good". |

lostwsga, lemans24 and their clones call banks 0x08-0x0f instead of 0x00-0x07, so they find nothing and test fails. By moving the CROM1-4 ROMs up 0x4000000 each you get the game to pass the test and lostwsga gains GFX, too. |

cause that would be a workaround and probably not the right way to fix it. |

Maybe, Riot City ROM test fail can be caused by banking issues too? |

IIRC Kale determined it's due to a bad dump |

[quote]cause that would be a workaround and probably not the right way to fix it.[/quote] Archived video by links below can say even more - that it's even NOT a way to fix it: athought game passes a memory test and get able to show a GFX besides the stump of "Insert Coin" label, the fore layers of tilemap are turing out to be garbaged, and the game itself all the same crashes soon - for this time bacause of "Fatal error: LSI53C810: Invalid SCRIPTS DMA opcode DF2B9480 at 001A2C50". https://www.mirari.fr/gKAl https://www.mirari.fr/MsOt |
