I can't confirm mspacman in particular, as I don't have that cart. But testing with what I do have, plus a collection of random loose software revealed nothing that worked. So I'm confirming your report. A cart from the vic10 swlist gave a black screen. Everything else simply booted up the inbuilt BASIC normally; the cart being ignored. |

The problem appears to be here: https://git.redump.net/mame/diff/src/devices/bus/c64/std.cpp?id=b8c338858a101d14308c64c87b0f714db4f05326 If I put back masks of the correct size for the cart I want to load (in the case of mspacman all 0x1fff), then it works. So a way must be chosen to get the sizes of the unique_ptr to again mask things correctly. |
