Also, please leave feedback if you do buy one, so that I can fix any problems you might have with the part. Speaking of finances, tell me if I should increase or decrease the price. I am unfortunately financially unable to test it currently.
If you are willing and able to get one, or brave enough to test it for science, be my guest. Unfortunately, I haven't tested to see if it fits or not. Here is the thingiverse link (in case you already have a 3D printer): That's why I came up with this! a 3D printed universal cartridge slot (by universal I mean japanese and american consoles only) The console will cost more if it wasn't tampered with (relatively speaking, as you need to clean it every now and then) Besides, you're destroying something that could be worth more in the future. However, I find it quite ugly, and it could hurt you if you don't know how to handle the tool you're using.
Using a dremel seems to be the best choice for me. As many of you know, the N64 only need to have 2 pieces of the cartridge slot plastic to be removed (DOESN'T WORK WITH PAL). Which means I either have to get an adapter or mod the console to get the imported games to work.
