Turbo EverDrive / Re: v2.4 SuperGrafx Glitches

« on: April 25, 2018, 08:50 PM »

V2s consume significantly less power than V1s. This results in extended battery life in Turbo Expresses, and less potential for video noise due to power line interference.

If you are getting the exact same issues that I had, then you are having pin connector issues. The reason that your V1 is working is because it's making perfect contact. Try reseating the TED v2, a hundred times if necessary. It took me months to finally figure this out, and finding the sweet spot might vary from console to console. After finding the exact way to insert my TED into SGX, I get 100% perfect SuperGrafx results, no pixellation, and no crashing.

Yeah, it's center negative so you do need to open the PSU and resolder -/+. It's a ten second job and that may be the source of problems actually.

It's really great to see that spare 4Mbit RAM chip being dedicated to GSU. This is the first time it has ever been used for anything, isn't it? It's so cool that Ikari left it on the PCB for devs to utilize for projects like this. Keep up the incredible coding, Redguy

That does sound like the kind of problem you can get from bad SD cards, and the TED tends to be picky about what cards it likes. You can also get those kind of errors when the TED isn't inserted exactly, so try inserting it all the way and then pulling it out 1mm at a time to see if it helps.

9V 1A should be fine, but if it's a generic PSU, you might want to try another just to be safe. You should be able to get a 2A or 3A on eBay (5.5mm x 2.1mm jack, center negative) for $2-3/shipped.

The issue with the Chinese knock-offs is that while the component on the PCB might SAY it is a certain value or rating, or even manufacturer, they very rarely are.  The sellers are able to sell the boards cheaply because instead of the higher quality, QC'd and validated parts from a reputable manufacturer that cost more money, they use counterfeit parts or parts from lower quality manufacturers.  Those parts are super cheap.

The differences can also be in the way the part functions.  The system checks will generally check to make sure the part is functioning at all, but won't check to see how they are functioning.  If program code is expecting something at Time X, but the cheap Chinese knock-off part is slower and provides it at Time Y, it can cause an error or bug that a higher quality component made board would not.

It's these types of errors which can be infuriating to those developing on a system, and also why there is no support for those knock-offs on these boards.  The guys working on these things don't want to spend their time trying to fix bugs which only exist on the counterfeit boards.

Exactly this. Many of us have learned our lesson buying components on Aliexpress and eBay. You'll order an IC or capacitor that claims to be one thing, but is something else completely. A good percentage of chips simply don't work or produce errors. I can't imagine an entire device made from that trash. Anyone doing electronic work quickly migrates to legit sources like Digikey or Mouser to buy parts, since it's the only way to make sure you're getting what you ordered.

They turned out extremely nice. Well done, Krikzz

If you buy a clone SD2SNES, you are taking a big risk of losing MSU-1 support since those Chinese counterfeiters leave those components off to save money. You also lose forum support and your warranty. You will run into ROM problems eventually due to everything being off-spec, and they apparently have appalling track records for supporting the Super FX core.

It doesn't even do anything. You can upload it, but you can't download anything. All you can do is create one and download that.

Dotsarecool's menu tool works perfectly. It detects your firmware correctly and creates a downloadable menu.bin. I just used it to create several themes and they're perfect with Redguy's new Super FX core.

The update is up, but I think it should be v08, no?
https://github.com/RedGuyyyy/sd2snes/releases/tag/gsu_v07

Fixed ram timing by adding additional fpga clock.
Fixed menu config save bug with gsu speed option.

Thanks for the great update, Redguy. Can your menu.bin be replaced with a customized menu, or is it required?

Same here, I never experienced the problem again after figuring out how to exactly seat the TED v2.4 in the SGX.

Unfortunately the DATs provided with that tool are 5 to 8 years outdated, and only work for No-Intro. So it's not going to be very useful.

But the SHA-1 you provided is exactly what is needed and allows anyone to use the exact ROM that you are testing with.

In addition to your console info (and NTSC/PAL), the most important info to provide is what ROM you are using. Without posting the ROM's source and MD5 hash, error reports are pointless. Redguy won't be able replicate issues unless you can tell him exactly what ROM you are using.

Thanks for the excellent update, Redguy. I tested it for a while and everything is golden. The now-fixed Voxel Demo looks pretty incredible

Just test whatever cards you have on hand until you find one that works. I use a generic Chinese 4GB card in my TED and have no issues, but I have ran into cards that didn't work with TED.
