How are the volume levels? If I can get an audio sample I will be able to tell you if you got the volume levels right or not (if you can use Falsion or The Legend of Zelda on Disk System, that would be ideal for me).

I just started my FDS library so I think the only game I have that uses expansion audio is Gyruss will that work? I tried to borrow a friend's Zelda disk but he doesn't want to loan it to me.
I'm not that familiar with how Gyruss is supposed to sound, but if I can at least find a dump of the disk, I can load it onto my Twin Famicom to check the volume levels.

Good luck with that. The TCT-6801 and Virtua Racing simply do not want to cooperate; everything I try results in the 3D graphics glitching out and the game crashing. I have yet to figure out whether it's a problem with the missing !CE_H signal on pin B26 of the cartridge slot (which can be faked by linking the pin to B11) or a bad Clock line. Whatever the case may be, everything I tried failed. Link B26 to B16 (this is the old way of faking !CE_H), game glitches and locks up; link B26 to B11, same thing; use the Clock line of a Genesis instead of the TCT-6801, it still glitches and locks up. I'm at a loss here and I don't have access to an oscilloscope, so I can't check to see what is the frequency of the Clock line on the RetroN3 (this is pin B19).

:!: :!: :!: :shock:

HOW??? There must be some connection to pin B26 on that GOAC. Try to find out which pin that links to (if it's even linked there to begin with) and take some pictures of this MegaDrive 2 clone's PCB if you can. I want to see this thing.

I think when there are two crystals on a GOAC-based Geniclone, it's usually to make it dual PAL/NTSC compatible. I highly doubt that has anything to do with the Clock required by Virtua Racing.

Get those images to me ASAP. This may be our only chance to finally get Virtua Racing working on the TCT-6801. All of my prior attempts have failed.

The 53.693MHz crystal is the NTSC master clock on the Genesis. Is this maybe the key to getting Virtua Racing to work? Most Geniclones I see only use a 14.31818MHz crystal, so it's possible the Clock line is running at the wrong frequency on the TCT-6801 due to the missing 53.693MHz crystal.

I just had a look at the page and man, someone needs to tell them that the RetroN3 Version 2 is discontinued. That's a Version 3 shown. Shows how little people know of this hardware revision.

But back on topic, you could get all the necessary signals for the lockout chip from those spots. Don't worry about it interfering with the Reset line on the NOAC and GOAC; the lockout chip will only be powered when the Super NES side receives power. Although the system shares a common Reset line, if the lockout chip doesn't receive power, it shouldn't do anything.

However, the 5V point shown is the common 5V point for the entire system. Don't use that as if you do, the lockout chip will be powered on at all times. Use the blue wire on the system selector switch to get 5V for the lockout chip instead. This wire is what delivers 5V to the Super NES side.

It has been brought to my attention that someone has attempted to use our work here to make a mod that they want to keep to themselves. this is not OK. I am deleting my half of the work that was posted in this thread to prevent such misuse. While I am all for people using the work to provide solutions to compatibility for others to use. it is not OK to attempt to sell that work or to keep it "secret" without sharing it with the modding and hacking community.
