Last post by P - October 22, 2026, 08:00:03 amYes even the old Everdrive that I have supports iNES mapper #90 and the new Pro supports even more mappers including NES 2.0 mapper format support.

Last post by UglyJoe - October 21, 2026, 08:10:28 pmI haven't touched it again. I was mostly just curious what it would do if I asked it.
At this point, don't flash carts already support pirate mappers? Seems like a solution to a problem that is already solved.

Buy / Sell / Trade / WTB boxed FAMICOM
Last post by tonev - October 21, 2026, 03:52:09 pmHello i want to buy a boxed Famicom. Preferably shipped from Europe so I don't have to deal with customs but in the end shipping from japan is also okay. Av mod is a plus but not required. Can pay by PayPal or Revolut. Or if you have only the box that also works fine because it is easier to find the console than the box.

Last post by P - October 21, 2026, 11:41:38 amThe Yamaha YM2149 used in Gimmick is a very common chip and therefore isn't very expensive. But you need to get it second hand from eBay or somewhere and there is always a chance that it's fake as some brokers relabels chips.
Some chips like VRC 6 are custom however and not found as discrete chips.

Last post by zombie343 - October 18, 2026, 10:30:15 pmFYI: I don't need to harvest the chips (and I wouldn't recommend anyone do that in 2026, given how rare/expensive these carts are getting).
I am still on the lookout for an authentic Gimmick cart. (No repros, no counterfeits, etc).

Technical & Repair Assistance / Famicom Disk System Motor not ...
Last post by Lizzaroro - October 17, 2026, 08:25:26 pmFor whatever reason, suddenly my disk system's motor won't move when a disk is inserted. I get the 'Disk inserted' chime when I put it in, but after about 2 seconds of silence, I get Error 2. I know it can't be the motor, because I tested it with a 9 volt battery and it moves just fine (Also it spontaneously moved on It's own at some point when the AC was plugged in, then it stopped).
I've tried everything I can think of. I've tried cleaning the board (The one that connects the power and RAM cable) with contact cleaner, using batteries instead of an AC adapter. I've looked ages online for a solution, but have never been able to find one. If anyone has had this problem, does anyone know what could be the cause?
P.S: One thing I should mention is that under the circuit board, the large M shaped metal thing that the Q1 B1009 Voltage Regulator attaches to is slightly rusted. Not sure if that would cause anything, but you never know.
EDIT: One thing I also discovered, was the voltage regulator component was reading 9V on both the input and output. Would this be a sign that the voltage regulator is going bad? Since I assume it should obviously output less.

Last post by fcgamer - October 17, 2026, 04:21:46 amIt works, but it really depends on what you are doing as well. Some things are quite easy to convert, others you start having to craw in the weeds.

Last post by UglyJoe - October 16, 2026, 06:56:13 pmTrying it out now with Codex using GPT 5.6 Sol.
Grabbed a random SMW mapper 90 rom and told it convert it to a standard mapper.
In like 15 minutes or so it gave me an MMC5 version that works in Mesen2.
Still some kinks to work out (it runs slower than with mapper 90, most notably) but I've hit my 5 hour token limit so will have to pick it back up later.
I'll have to ask it later what its loop is doing, but seems to have decompiled it, written some mapper shim, and used cc65 to compile things back together. Runs tests using Mesen2 and lua scripts.
