TED 1.2 crashes (only on CoreGrafx, only certain games)
« on: February 22, 2018, 12:00 AM »
I have CoreGrafx crash issues with my Turbo Everdrive V1.2.

Only on the CoreGrafx, only with TED 1.2 and only certain games.

Here's what I have...

TURBO-ED Version V1.2 / 07.05.13

OS Version    : 4
Firm. Version : 2

TURBO-ED V1.1 / 07.06.12

OS Version    : 4
Firm. Version : 1

Console Hardware

Duo-R
CoreGrafx
GT
TurboDuo
TurboExpress

TED 1.1 works fine on all systems.

TED 1.2 works fine, except on the CoreGrafx.

TED 1.2 crashes with (probably more demanding) games like Air Zonk and Parodius after a couple of minutes, but just on the CoreGrafx.

Other (probably less demanding) games like Bomberman 94 do not crash.

And this what I already tried...

- tested on 2 different un-modded CoreGrafx consoles (No-Intro Air Zonk, Parodius, Bomberman 94 ROMs)
- tested with original Parodius HuCard (works fine, no crashes)
- tested with another PSU, instead of the original (doesn't help)

Any ideas what the problem could be?

Does the TED 1.2 probably draw too much power for the CoreGrafx?

PS: My TED 1.1 stopped working some time ago. Contacted krikzz' customer service, which was very responsive. Sent the card and it was repaired for free. I don't even remember when I bought it. This is real customer service. Respect!  8)

I have TED 1.2, previously I had TED 1.1 and with both I have/had issues on CoreGrafxII (original pad from CoreGrafx II). Now I'm testing original PC engine (white version with white pad without autofire) with Megadrive PSU and so far Coryoon works fine. Looking at other people problems with generation 2 looks like does not make sense to upgrade :/

Both systems were tested with Tennokoe unit modded for RGB.

The only special thing I know about the CoreGrafx is that it may sometimes have the revision A of the HuC6280 CPU which the SuperGrafx also is guaranteed to have. The GT may also sometimes have the HuC6280A CPU, not sure about other models.

The HuC6280A is supposed to have fixed a channel amplitude centering bug in the CPU's sound chip. But this bugfix may also cause a clicking sound in some games that was designed with the original HuC6280 PSG's behaviour in mind. Mednafen can emulate both versions of the CPU.

In the meantime, I bought a TED V2.5. No crashes on the CoreGrafx so far.

It looks like only my V1.2 does not work properly, only on the CoreGrafx. No problems with V1.1 and V2.5.

I'm wondering if other people using TED V1.2 on CoreGrafx have the same issues (see 1st post)?!

No crashes on Air Zonk on my v1.2, played far more ten minutes, till I lost all my lives.
