Is there a simple way to convert a bin or XEGS cart image to R16 format so it will work with MYIDE ][? there is a new game wee ninja that I cannot seem to get to work on the atarimax cart i have - any help would be wonderful.

if anyone can help me make the A8 binary on this thread work I would be much obliged! I just cannot get it to work whether I use all the available cartridge creations options are out there:

Back sooner.....

Ok, no idea any more.
I looked through my files and it is all done manually back then.
Changing all STA $D500 to STA $D50A (or STX or STY or relative store at this address).

The bankswitching-address is $D50A on MyIDE-][
Where on XEGS-cartridges it's $D500

The R16 extension is for the fat-loader software to use 2 banks of 8k, instead of the default single 8k or 16k roms.

That was 13-14 years ago.
My brain starts hurting looking at this, so I leave it.
Aks the programmer to compile a version using the other bank-code.

Grtz,
Sijmen.

Let's see how this works out.

I received a R16 version for testing.

Fast reply btw. :-)

It seems to work nicely.
So I asked if I can share or he want's to add to his post on AA.

Later!
