Will add more to this issue when I have chance to work to on this emulator again.

There's a vdp test rom that tests a bunch of things. I pass the first page, from there it goes downhill with a lot of failed tests. Great thing is there's a well documented readme for each test as well as source code for the test itself.

I think some of the tests are irq timing related which will be a huge help and may fix (or break lol) the remaining broken games.

Theres some sprite tests that I fail as well, mainly collisions of offscreen sprites etc.

Test is found here https://www.smspower.org/Homebrew/SMSVDPTest-SMS
And here's the thread with some useful discussion https://www.smspower.org/forums/10695-SMSVDPTester

parse sprites when screen disabled, check sprite collision regardless…

… of bg prio

parsing the spirtes even when the screen is disabled means that sprite overflow
can occur.
this was needed to pass one of the vdptests.
