Just fixed a CPU bug where something was just slightly off by one. That was a tough one to find, but more test ROMs are working now.

I started out with an 18MHz clock speed on the Pocket, which ought to be more than enough for everyone right? 😅 I’m gonna try to see if I can increase that speed. Maybe I can also get some more instructions to complete in fewer cycles. Then finally, I’ll go back to working on sprites!

@tsalvo Oooh! You've got the chibicc example going :D

What was the CPU bug btw, I'm curious if maybe I can't add a note about it in the docs?

I'm sure @lynn and @hikari would be happy to see this :)

@neauoire @lynn @hikari it was 100% on my end. In the SFT instruction I was shifting by a 2 instead of a 1, because I had copy-pasted it from SFT2. Took me forever to find, but it was totally my fault!

After increasing the clock speed, and a couple other minor improvements, it’s a little smoother now!
