I found a larger drive Mitsumi MR535-U00 (physically twice as large as the supra but works but doesn't fit :(...

Re: 16BIT ROM CART THOUGHTS

Yep. It's not so much what the CPU does but what the code does. If the code does a 8 bit access for some reason, it will use /LDS or UDS (depending on the address). The code part will always be read as 16bit as this is the minimum instruction size. The data can be read in 8 or 16 bits depending on ...

Forum sections updates

IngoQ suggested we "section off" the forum as the list was getting long.. so I have made a start on this...

There's a lot of permissions to copy around also.. so if anything "odd" happens then let me know..

Also note that the main download sections are only available to registered users.

As I got distracted with my 2600 console lately, I plan to do some minor repairs and upgrades to it in the near future. Though as this forum was intended for generally 16 bit machines, we did not really have a section for 8 bit machines and consoles. So the new section is open now, and I don't mind ...
