What setup are you using to test your program?

The Cuttle Cart can only support games up to 64K and the bank at
$1800-$1FFF is fixed at $F800-$FFFF.

In version 2.10 of z26 3F games should work as you assume. Also files
larger than 64K should automatically be detected as 3F games. We only
had one 512K file from Andrew to test this though.

In version 2.09 support for larger 3F games was a bit of a hack. The
bank at $7800-$7FFF was still the fixed bank and you had to enable
3F bankswitching with the -g11 comand line switch. If you are still
using this version, it would be best to download the newest z26

In Stella there also is support for large 3F games. I think it
automatically detects 3F games if there are several write accesses
to address $3F. Otherwise you would have to create a special entry
for your game in the STELLA.PRO file.

Ciao, Eckhard Stolberg
