Hi everyone, I have a working/SALT tested Atari 800 48K and two new MaxFlash 8mbit cartridges. From what I gather reading the forums (now), multicart images won't work on an unmodified Atari 800 48K (whether <48K ROM, .exe or .xex) due to paging limitations? I can get individual 8K cartridge ROMS to work if I copy over ~10 copies of a single game to an individual MaxFlash, and that's fine by me as a workaround. But I was wondering if I understand the limitations correctly (I'm going off mainly forum answers to 400 users), or whether someone with an original, unmodified Atari 800 48K has a MaxFlash image that works for them or advice on making workbooks or modifications. Thank you! MJC

You need 64k to be able to load other then 8k .rom files.

Yes I understand that, but I should be able to make an 8K rom multicart, correct? All I can get working is a single ROM copied multiple times and am just wondering if that's all that works on an original 48K 800. Thanks!

Yes, you are correct.

On the 400/800 with no extra (16k) RAM in the OS-region you can only make compilations of 8k ROMs.
That is what you have, so NO support for exe and atr loading, for as I know.

All 8k ROMs should work.

Perhaps the one or two odd ones out, that interfere with the bankswitching of the maxflash need to be a patched version.
I and others made some of these and uploaded them on the forum.
From my head, fort apocalypse and gyrus need to be patched.

Grtz, Sijmen.
