Would be fine to have Gradius II possible - great shooter I think and Turtles is also fun to play. Thx

No chance? 😢

I started work on mapper 25 and the VRC2/4 family generally a few weekends ago, got all the basic bank switching working. The IRQ timing is rather complicated and I didn't get it working correctly on Gradius. I'm going to need to rewrite that, maybe I'll have some time to try again today before I run out of weekend.

Thank you - I appreciate your great work!
