I recently got myself a 7800 and then had it modded with svideo. While most games on the system run fine, some run horribly. Specifically dig dug. The video is u stable and jittery, some games have weird artifacts or jailbars. Some games run un black and white and the screen is pushed down.... I bought a flash cart thinking that would help, and the results for these games are the same. On camera dig dug looks fine put the video shakes up and down and the monsters glitch all over the place. Do I need new caps, or voltage regulator? Can it even be fixed? Thanks!

Just now re-flashed the BIOS and still getting the same results sadly.

Heres some pics of the issue:

First off I'm aware of the display issues with modern televisions. My problem is the same issues are happening even with a CRT. The menu items are completely garbled and impossible to read on any TV. I'm not sure how to tell if its my Atari 7800 (Which has been S-Video modded) or the Harmony cart itself. As with most people the games run fine when you select them, its just impossible to know which ones you are choosing. Thanks in advance for any help or advice!

You should make a redesigned atari 5200 controller.

I have lynxman flashcart and I love it

Cant wait!!

Same boat, I emailed twice and no reply. I'm hoping its not discontinued.

Please add me to the list for a Lynx 2 flashcart with case. Thanks!

Ive messaged Mateos on his site awhile back but no reply Anyone know of these are still being made?

You should team up with StoneageGamer.com. I bet they easily sell your flash carts like hot cakes! I think maybe there is a lack of awareness of your product perhaps?

Thank you so much for the reply! I found the pin out for the sound chip https://en.wikipedia.org/wiki/Texas_Instruments_SN76489. Does Pin 7 look like the correct pin for sound out? Also I wanted to ask if there are some good instructions on how to build a simple composite out amp/buffer, (Provided that I need one of course). And Last question, a stupid one, but can I solider the ground wire to pretty much any metal point? Trying to find a good place to get ground from without hopefully frying the board.

Does anyone have instructions on how to mod a SG-1000 for composite or even s-video? I would be super grateful for any information on how I can mod my system (Its not a MK II just the original SG-1000)
