Where can we find ALL the firmware revisions for testing? RetroUSB only lists the current and original 1.10 firmware, and I cant get Megacat Studio Creepy Brawlers to work right either. The sprites look all wonky.

  PM sent. It has been requested not to display the links publicly, but they are easy to find and download. Try b6 or b7.

"AVS-v1.20b7.bin" presumably works with all the Mega Cat Studio releases. It is what I used to get Creeping it Reel working. b8 and 1.20 final are presumably "no change" if the readme file is to be trusted.

That's good to know. Presumably the 1.20 firmware on Brian's website is an exact copy of 1.20b8. Perhaps a v1.21 is in order? I don't really think there's much change from b7 to b8 so I may downgrade my AVS. Thanks for figuring this out...  

@Ferris, the AVS manual mentioned you could enable horizontal overscan to display the natural background color of the NES pallet. This feature presumably got nuked in v1.10.  I upgraded almost immediately after unboxing my AVS, so I never got to fiddle with the v1.00 firmware. As far as I know, there's no way to downgrade below v1.10. Just kind of curious what if any menu options were axed after v1.00. Sideband colors were something no emulator ever supported, so it would have been cool to render it visible for a "warts and all" presentation.

MegaCat was nice enough to send me the files to test it out on my AVS, and I was surprised to see it booted! Checked my firmware, I was on 1.20b6.

Upgraded to 1.20b8, game no longer boots. Upgraded and downgraded back and forth between the two versions, will not work on 1.20b8 firmware on any attempt. Just boots to a black screen.

I tried 1.20b7 and it still works, so something must have gotten broken in the most recent update.

So downgrade to 1.20b7 and it should boot up properly   ]]> Mega Cat Studios: Creein' It Reel... http://nintendoage.com/forum/messageview.cfm?catid=106&threadid=178150 2017-11-14T20:20:55 -05.00 Kosmic StarDust 17
No NT Mini on the cards due mainly to price point, but I do have a Super NT on preorder.   ]]> Mega Cat Studios: Creein' It Reel... http://nintendoage.com/forum/messageview.cfm?catid=106&threadid=178150 2017-11-14T20:03:09 -05.00 Kosmic StarDust 17 Originally posted by: Kosmic StarDust

It's most likely just an AVS problem. If it works on an official NES console, but not on the AVS, it's not a board problem.

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. ]]>
