Supergrafx vs Everdrive freezing in Daimakaimura

[iCach0]

Thank you! My hope is that Krikzz addresses this at some point with an explanation. I've also posted on his forum and tweeted him about it so fingers crossed!

In any case I'm grateful for the recommendation!

I had very similar issues, but luckily mine were resolved by cleaning the cart slot and finding the perfect way to insert it. I'm also using a regulated 9v (2A I believe) aftermarket power supply if that matters, and my SGX is recapped and RGB amped.

I'm convinced that the SGX problems are related to the PCB thickness of v2.4. The thickness of the v2.4 carts varied greatly due to some new supplier Krikzz was using. See the pictures here. My guess is that he might have standardized the PCB thickness again in v2.5.

Same here, SGX recapped RGB modded and using a RetroDC PSU. My TBED is 2.4 as well and I'm experiencing the same glitches.

When you say you're convinced it's a thickness issue, do you know if it's thicker or thinner than it's supposed to be?

Hey glad you made it over here! I was the one in MLiG live stream chat who told you to stop by and see if anyone here could help you out

Hope you are able to get the issue resolved, there are a lot of smart people here who hopefully can give some insight into the issue

For those that dont follow the SmokeMonster thread in Everdrive forums, Krizz dont had these problems with TED 2.4 (all games work fine in his SGX) but gaves a possible explanation:

Most of TBED v2.5 use new revision of PSRAM memory chips, which i start to use recently instead of old revision. May be this is why they working (if tested both on same console). During genesis mega x3/x5 development i discover that ISSI memory chips has problems with refresh mechanism at some conditions, but at same time i discover that ISSI start selling new revision of their psram chips (TBLL markering on the package instead of BLL). I ordered few samples for test and they all working just perfect with mega x3/x5, i decide to use new revision of chips for TBED also. Anyway i can't say anything for sure about problems with SGX, because i can't reproduce any of mentioned problems on my SGX  with TBED v2.4, even with old revision of psram chips. I tested all games, then i leave working Daimakaimura for few hours, but nothing happens. May be it happens only with specihic SGX motherboard revision, or only with specific pait of cart/console.
