I know I've contacted RetroUSB support for an incompatibility with some of my MMC1 boards (which work perfectly on any official and clone console), and they have yet to even address it. That was a year ago.
EDIT: I wanted to add that even the ones that had issues on the AVS worked fine on a Analogue NT mini.
Hi thanks for the reply. It definitely appears to be a quality PCB with 5V chips, not like that asian junk the repro boots are made of (and sadly a few legit homebrew like 8-bit Music Power et al...)
I'm still curious to know why the AVS doesn't like these games, but it appears to be an issue across several of your PCBs. Something appears different to the console compared to normal mappers. But yeah, if it works across all real hardware, clones, and the NT Mini, then something on the AVS side?
Yeah everything there is in happy +5V land
I always assumed it's something to do with the timings in my mapper, but I haven't been able to iron it out because things work perfectly on any other console I try without fail. Even PAL consoles behave as they should. It's
ONLY with the AVS. I asked how they check and initialize their carts - in order to see if there is something I can tweak on my end - but again I haven't received any response from them.
I'll email MegaCat and see if they can send me a sample so I can test it on my AVS here. Maybe I'll be able to get some more info to pass off to RetroUSB for some kind of future fix.
