I had an Amiga ship from Poland and it took their government 2-3 months before releasing it to the US. So it might depend on where its shipping to. Russia also since COVID takes months for anything to get here (I ordered Famicom Lightgun).

Yes with two .a78 roms labeled inside the zip. * Rampage (USA) (Doesn't work, bad header).a78 [sounds like this had no header which seems wrong for its file ext as you said] * Rampage (Works with potential graphic glitches).A78

Rampage.7z

It ran then this graphics glitch started to happen less than a minute into gameplay. Also tried another rom & got this screen. Hit fire & it gets stuck at 90% on this rom.

I bought this PSU which had one but still needed to add an extra ferrite core on PSU & some other lines. https://www.amazon.com/gp/product/B07QV8CCJ5 Got these ferrite cores which worked well for me in case others in same boat as me. https://www.amazon.com/gp/product/B07CWCSNW9 Can tuning get off on 7800? I wonder if its something I should double check on my system.

So you have the purple PCB? So people with green PCBs and POKEY installed haven't had firmware upgrade issues?

Got my ferrite cores. Put them on both ends of video cable, power supply (which already had a small one) & the power line between cart and console system (which made the most difference). Much cleaner image now & I'll get a better power adapter later.

http://www.best-electronics-ca.com If you read back in comment though it sounds like you should hold off on installing POKEY until a later firmware update though. Also read back in comments to find out what SD cards have worked for people if you have trouble there.

I'll try some others and see. Ok thanks, I'll order one & give it a try. Good idea to try if the cart doesn't have any electrical reason that could cause issues?

Awesome POKEY works great. Cart working good overall. One thing I notice is the cart does add some video signal noise I don't have with other carts.

Will possible future firmware updates be published here or is there an external URL to keep track of for that?

Ugg silly me. Just blanked that existed. k tnx.

Ok thanks. Did I miss this in the forums or you get that from external / other URL? Wondering if firmware update will only be listed here or some other site as well.

Just got the cart today. What is the cart input power requirements? Volts & Amps? Also what is the power supply polarity? Are there diodes to protect against this if DC voltage is reversed?

I email "[email protected]" (no reply yet) as I didn't see an order forum so hope to get one at some point soon & plug it in when POKEY testing is more ready.
