I know you suggested I try my own, but I had too many issues when I did.
So I'm trying yours again, but this time I just turned off Rhodium. So far, so good.
If you would consider sharing your SYS & ROM files that you used to create the 21231 ROM, it would be truly awesome and appreciated. When I extracted them from the posted files and dropped them into Calkulin's kitchen [4.7] I just kept getting different errors every time I tried to correct one.
I love what you've done, but I want to get rid of Rhodium entirely- if for no other reason than to be able to have that extra space available for my own stuff.
