 08041: fds [smb2]: Game frozen at title screen (it should be animated). |
||||
| Description | Not much to say beyond the summary. Many games seem to have issues related to disk access, though having just looked at cartridge bootlegs of this game I know they can be frozen on the title screen if IRQs aren't working properly. (Though this could be one and the same, since the BIOS uses the same IRQ line for disk access.) | ||||

As a general comment beyond this game, should fds even be marked as working? 54 of 309 entries in the software list are marked as supported="no". About a year ago I started (and didn't follow through) testing supposedly supported fds games and quickly came up with 20 more that immediately freeze, don't load, have a save disk error, backgrounds don't scroll, etc. That was just from starting to go through the software list in order. I suspect the non-working entries to actually be 100+. |

I think a lot of the bugs with the nes/fc/fds emulation are to do with the ppu impl. not being cycle-accurate. |

Sorry Tafoid, I think I wasn't clear in my description before and I've changed the category back. The game is definitely frozen as soon as the title appears. This is more than inputs not responding. Mario should be on screen, the "2" in the title should color cycle, a turtle should come hopping in, and then the whole screen should scroll seamlessly into a demo mode. All of this should happen without any input. |

Turns out the FDS' timer-based IRQ wasn't firing at all. Seems like it must have been a regression based on other reports. Fixed in https://github.com/mamedev/mame/commit/9eccbfde84b0148660f172d4ec04eb49b2400796 |
