Universal C64 1MB cartridge

To be exact, storing a number in any address between $DE00 and $DEFF will switch the bank (or disable the cartridge if bit #7 is 1.
Also, setting a bank "that does not exist" (like bank 8 on a 64K rom) will set it to bank 0, bank 9 to 1 etc, because the upper bits are ignored.
This behavior is actually emulated ONLY by VICE in full and by DENISE emulator. Not by the U2+ and not even by some fpga solutions.

Hi Marko Is it possible to use this PCB to create regular 16k cartridge? Only one 16k game but using W27C020 eprom. This is what I have with me :)

someday i need to try M27C801-100F1 as for 1mb :)

also M27C4001 works! just need to set for 27C040

this cartridge also uses M27C1001 eproms ive just burned double dragon ocean and it works

is posible to use this memory? 27C801 1mb

This is a great design, very useful, thank you Marko for sharing. I have two subjective suggestions for you to consider, if you ever want to further improve this one: 1. Consider removing default connections between jumpers to avoid cutting tracks (mode/lock/size/md) it's much easier to short solder them than cutting 2. Reset compatible with angle tact switch is more universal, like the one used in your C64 Magic Desk 512k Cartridge which is also great BTW. Cheers Mateusz

What's the difference between this cartridge and this one? https://www.pcbway.com/project/shareproject/C64_Magic_Desk_512k_Cartridge.html

hello i just received and mounted the card with robocop 2 bin, but i can't get it to work. I followed all the instructions. I am attaching the photos. did I do something wrong? I didn't put the touch button, but I don't think it's necessary.

Hello, I bought this pcb and I am not able to make the bin for the Prince of Persia, I do not understand the instructions to do it. Could you pass me the patched file? Thanks

Fits perfectly in the Retro Innovations cartridge shells. https://store.go4retro.com/c64-sx64-c128-c128d-cartridge-enclosure/ I was even able to use sockets for the chips and still fit in the shell.

Thanks PCBWay for perfect PCBs :) Thanks msolajic for sharing this magic cartridge :)

Genius Marco ! Thank you for this Great Design. I am very happy to have a POP cartridge, thanks to you.

Can the cartridge handle the bank switching requirements of games like super zaxxon? thanks.

can I ply Toki(ocean) with this?

Thank you for your participation in our 3rd PCB Design Contest. 7 Tips On How To Make Your PCB Entries Stand Out 1.Choose the appropriate color of soldermask and silkscreen for your PCB project. 2.In addition to the PCB images generated by our website, you can upload more photos of the project. 3.The more detailed project’s description is, the better judges and other makers understand it.
