Looking for info on these two chips. They seem very close related to the 5682 single asic game gear based on my research so far. But I'd like to know the pinouts of these 2 ICs to understand them better. This is from a later release of the tectoy sms 3 compact.

I have no info to provide, but can you please run this test (VDPtimingtest4.1.sms)?

I'm trying to understand something...

Wow I'm a bit late on this huh? I will try and do the test for you soon because I want to know whatever I can about these chips.
