At least with the Retron 77, I found the cart dumper could be very finicky. Sometimes it could take many, many times to get the dump to work even when it was a clean cartridge. Or if the cart was even the slightest bit dirty it couldn't read it.
I know Rampage didn't work from the cart but does it work from the Dragonfly? Rampage works with the pro system emulator in RetroArch and I am wondering if it was something with the cart itself?
Ultimately your best bet for that is a scaler like the RetroTink 2x or 5x and a console modification. Crossbow here on the forums modded mine. He did awesome work. I started by getting the scaler. I hooked my 7800 up through the antenna of an old vcr and used the av out to the RetroTink 2x. Then a little bit later I had my console modded.
Yes! We should call it Demon Attack!
Thanks for the kind words! We are working on a follow-up to Lashing The Feral Swine. We have about 9 songs in various states of completion.
Mike is great dude! Easy to work with.
Yep. I have raspberry pi running lakka with Stella 6.0 no issues on that TV. As well as consoles hooked up to a RetroTink 2x without issue. I also tried the hyperkin megaretron hd without issue. That being said the TV is old (2011 I think). It might be on its way out. I have been using the retron 77 on that TV for 5 years now so it's definitely weird.
Does anyone ever have issues with your retron 77 sporadically losing the video signal on 6.5.3 or 6.6. I have an older Retron 77 so it shouldn't have the faulty ram issue. When I switch back to the original firmware, it is fine. It didn't used to have issues.
