low_budget Posted October 31, 2012 Author Share Posted October 31, 2012 The NES Super 8 does have stereo sound and an improved pre-amp. There is no microphone support. I didn't see much point in adding it since only a handful of Japanese games use it. Just tested Super Mario Brothers 3 today and found it didn't work. It plays fine on the Powerpak, but the original game won't boot. The NES Super 8 needs 100% compatibility, dammit! I'm assuming the extra work RAM on the cartridge is the issue. I know the cart is good because it works on my original NES. I'll be working on this issue this weekend and I have some more parts coming in so I can work on the composite video. The ram I used is 10x faster than the original NES memory and that on the SMB3 cart, could that be a problem? I'm wondering if I could configure the Super 8's onboard memory to 4k (for CPU and PPU) and disable any extra cart memory, but I'm not sure if that would make some games incompatible that are currently working. I have 2 extra v1.0 NES Super 8 PCBs on hand, if anyone is interested in helping me troubleshoot this issue, I would offer a reward of some kind. I could sell a v1.0 PCB with parts to an electrically inclined individual for $80, and if they are able to help me correct the problem I would refund that cost and offer an extra $30 (negotiable.) I wanted to get as much done on the project as I could on my own, but I'm not afraid to ask for help. I have also started work on v1.1 of the Super 8, but I want everything working correctly on v1.0 before I have v1.1 manufactured. Quote Link to comment Share on other sites More sharing options...
