My mistake

Didn't know that key pass controller firing direction. It was not fun trying to play just using the touchpad only.

Vanguard. Its also twin stick.

I wish them luck and success. However I have no interest in this. I just have no interest in these emulator systems being marketed as remakes of classic systems. Remakes of classic carts or new games in the style of original games are not for me. If I want simple moderns games I can use my phone or tablet. But I do hope they are successful. For this interested, would you still be if "Intellivision" was removed from it?

I finally purchased a Hakko FR-301 desoldering iron. If you can afford it, I highly recommend you desolder using that rather than a Souldault. Including time learning to use the tool, it took me about 45 minutes to remove chips from 40 pcbs. You will save a lot of time and effort with the FR-301. It is so easy to use and does such a good job, I had a lot of chips just falling out from the pcb. Pics are example of how good it desolders.

Two assembled. I'll program tomorrow.

Just sent PayPal for 2 boards. More parts to order. I'm thinking of building these in a case. Thank you Scott

There are no lablels on the pcb for: C1, C2, C5 and C6 (0.22 uf) C3, C4, C7 and C8 (0.1 uf) Which caps go where> I watched the utube video in the first post to try to copy that. However there are only seven caps on that board and the layout is slightly different. I think I have it following the schematic but am not 100% sure. Thank you

Also, if you have 2 extra boards I'd appreciate a chance to make a couple.

Is there any way or need to adjust up/down and left/right resistance values? I built a 2600 to 5200 adaptor years ago. I can't find the source, but there are 2 pots for adjusting those values.

Thank you. One set just pre-ordered.

Received the 2 PCBs. I've ordered parts from DigiKey. Will post after making them.

If you have more, I would appreciate being able to get 1 or 2 (2 preferred) Thank you

I suggest a time out. Just forget this thread for a while. Its not even enjoyable to read anymore. In the big picture it does not matter who is right.

No problem. Ask any questions you have either on the boards or by PM. If you are going to be removing ROMs from a volume of old cart pcbs, I'd recommend you get a desoldering tool such as a Hakko FR-301 (or the prior version FR-300). I finally picked up one last week and wish I did so long before. Including the time learning to desolder, it took me 3 1/2 hours to remove ROMs from 40 cart PCBs (3,200 legs unsoldered). Really a much better way than what I posted in that thread.

I have the old version with RGB output. It needs to be run through an OSSC or Frameister XRGB mini to display on a modern flat panel.

I did the same thing. +100 on everything ApolloBoy says.

Its very easy to create split ROM carts

What ??? Sound is excellent. Now I'm wondering what goes on in your mind. On second thought, I can guess what stage of life your in. Enjoy it as it will pass quicker than you think.

No. I'm talking about the Sophia RGB board that comes from Poland. Just looked up DVI Sophia. It looks like Simius makes both. The RGB is an older Sophia version. I do not have a DVI Sophia so I cannot compare to the old Sophia. I'd recommend the RGB outputting Sophia if someone wants RGB output for their 5200

The Sophia taps the Atari 5200 video chip and creates an RGB output. Much the same way the NESRGB works. I installed the Sophia on my NTSC 5200 and connect the RGB output to a Framemeister RGB mini. Picture is pixel perfect, colors bright and no interference of any kind. I'd recommend the Sophia if you have a way to display the RGB output. OSSC are slightly more available than Framemeisters.

I had both svideo mod and Sophia. Without doubt Sophia provides better clarity and more vibrant colors than svideo. Big but though. To use the Sophia rgb output you will need an rgb capable CRT or a device such as OSSC or Framemeister RGB mini to go to a modern flat panel. Both are easy to install.

Do you have the OshPark link for the Grips 5200 joystick pcb?

No disrespect intended but the 5200 games have simple control scheme designed to work with analog stick (steering) and digital buttons (gas / brake). Just don't see how pedals would add anything unless game code is rewritten for analog gas / brake input.
