SuperGrafx Game Compatibility Glitches - Super SD System 3

ShootTheCore

Giga Shock!!
I've been using the Super SD System 3 with my SuperGrafx system for the last couple of weeks, and I've had a few compatibility glitches that are consistent and reproducible. I've tried different rip downloads of the games and experienced the same issues. I also play with the soft reset feature disabled all the time.

I wanted to document them here, partly so NeoDev and NeoSD can be informed, and partly to see if other SuperGrafx and PCE users are experiencing these glitches as well.

The issues I've seen so far:

Rayxanber III: Game resets when fighting the second level boss.

Steam Heart's: Intro plays fine, but after starting the game, it freezes up after about 5 seconds.

Hello,

Could you open your supergrafx and see if the pcb is corrupted ?

This is how my own supergrafx was (i noticed it cause i had issues)

This guy had the same exact issue as me

Worth to have a look inside there

I just tried Steam Heart's and yes, it hangs when the game starts, when the characters starts talking. Looks like an ADPCM state emulation issue, should be quick to fix, as that game worked perfectly (in fact, we used the Steam Heart's intro to check the proper emulation of ADPCM streaming and in game for the voices streaming too)

I tried Rayxanber III, but I died a ton of times before reaching boss 1, that's going to be though to test :)

I actually recapped my SuperGrafx, did the jailbar fix, and gave the board a good cleaning when I got the NeoSD shipping notification because I wanted it to be ready. Here's pics of my board. I didn't see any trace corrosion issues. I imagine that if I had hardware issues, I'd probably be seeing a lot more problems than just those two games - I haven't had problems with any other titles across many, many hours of gameplay.

Yes, it looks like a software issue, neosd was able to reproduce it and its working on it. I just wanted to rule out the hardware issue cause there was a gap of weird flux on my supergrafx pcb so after seeing the assemblergames post i thought this may be an issue others may have.

If you want to speed up the procedure, send us an email with your serial number to contact@neosdstore.*** we should have a firmware update soon.

Thanks

A quick question about Steam Heart's. Are you letting the characters do their speech, or skipping it? If you are skipping, you must press RUN twice, because the first time skips the speech AND pauses the game (go figure who designed that...) and then must press it again to unpause it.
Yesterday I made a quick test and it blocked when pressing RUN to skip it, and I thought there was a bug there, but this morning I somehow pressed it twice, and it continued properly, and I remembered that quirk.

I didn't even know that there was opening speech, or that it was skippable by pressing RUN twice. I hadn't played the game before. Good to know that I can skip that part to still play the game until the new firmware is ready.

So, where is exactly crashing for you? when you press RUN in the main menu?

It's hanging for me where you described before - after you start the game on the title screen menu, after you select a character, you see the space ship launch onto the screen for a second, and then the game freezes. I just checked a video of the game on YouTube, and it is indeed freezing when the character speech starts.

I can make a video of both games glitching on my hardware if that would be helpful.

Also, I've just barely sent my serial number to contact@neosdstore for the firmware notifications. Thank you for your support and for making a great product.

Hello,

Got the email.
Neodev has tried it again now (on coregrafx and pcengine) and he can´t reproduce the issue, it works fine on his setup.

I will try it tomorrow morning on my supergrafx, its 23:44 now and i have to get some rest.

We will let you know tomorrow

I'm sorry for you and for the SuperGrafx consoles (for sure the TerraOnion team will make an update and the problems will be gone) ... but i want to tell you cause the Steam Heart's: Intro plays fine/ normal , and after starting the game, the game runs flawless on my CoreGrafx II ... so , i don't know if this matters or no in the future ...also i can test these games on white PCE console , Monday.

Follow up with some good news. I had a friend suggest flipping the compatibility switch on the back-right corner of the SuperGrafx to see if it resolved the issues I was having with the Super SD System 3 and Steam Hearts and Rayxanabar III. The switch disables the enhanced SuperGrafx hardware.

It turns out that flipping the switch did resolve both issues - I was able to play four stages into both Steam Heart's and Rayxanabar without any freezeups or reset issues.

So it may not be a SD System issue - these two titles may have compatibility issues on original hardware. Unfortunately, I can't test it to find out since I don't own a CD-ROM drive setup for my SuperGrafx. But until we know for sure, flipping the compatibility switch is a great workaround.

Good to hear as I'm going to be using a SuperGrafx myself.

That's interesting. I completely forgot about the compatibility switch in the sgx. Glad to know it worked. That means that probably they sill also fail with an original super cdrom system in a sgx, that's something I'll need to try.

So the real question then is it possible to "fix" the compatibility issue within the SSDS3. Extremely low priority (not really a bug at all), but it'd be cool if it was possible.

If nec put the swich to change from coregrafx to supergrafex compatibility, it was for a reason for sure.

From a design point, putting this swich is totally wrong as it adds an extra cost and it gives troubleshooting to the customers, so i think they had to put it due design limitations.

Agreed. Very little info online about what games fail in Supergrafx mode. The only two I see reference to are Space Harrier and Double Dungeons - W

If I can get enough rest to find the time I'll try runnin Rayxanber III on my SGFX as I know I have a copy of that game. I don't think I have Steam Hearts though. Both my SGFX & Super CDROM2 were NOS units and they're still low hours after I started using em.

When I had my Supergrafx I remember having problems with Night Creatures (TG16) working on it. And I don't think it played with the switch in either position.
