simple cartridge replacements to large ROM/RAM boards. This cartridge I had named 'The Penultimate Cartridge' as there seemed to be lots of revisions of Ultimate and Final Cartridges for this and other systems, so I thought I would be honest.
SD2IECs from thefuturewas8bit.com, here is my modified cartridge next to a VIC20 coloured SD2IEC.
I've managed to squeeze more cartridge images into the ROM by doubling up the 8K cartridges. I had considered this with the DIP switch version, but didn't have enough switches. Now it's under software control, I can fit two 8K images into each 16K bank and address them separately, so there could be up to 62 8K carts on the standard, or 31 16K carts, or a combination of both. There are now 37 cartridges on the menu, and space for a few more.
I've added support for joystick navigation to the menu. Up and down moves within the displayed page. Left and right change page. You can also scroll down onto the next page. Fire loads the ROM.
The firmware has been updated to v5.0a, with the total up to 43 ROMs. The uncased versions are still available above. The custom cased versions are now available to preorder now from www.thefuturewas8bit.com.
There is a user guide if you need any further information.
The first run of cartridge is now here, more photos of those and the test program.
