SignGuy81 Posted April 9, 2017 Share Posted April 9, 2017 Here are some pics of my modded flashback 2. I'm not done yet though I'm going to add an LED for power and I am going to put in a switch for automatic switch between cart and internal. Just wanted to show my progress so far with my 3D printer and freecad. 14 Quote Link to comment Share on other sites More sharing options...
SoundGammon Posted April 9, 2017 Share Posted April 9, 2017 Nice! My idea, when I get the time, is to build the Flashback 2 into a Sears Sixer! 1 Quote Link to comment Share on other sites More sharing options...
Skippy B. Coyote Posted April 9, 2017 Share Posted April 9, 2017 Awesome job! Ever since I learned to solder last year I've been really wanting to add a cartridge port to a Flashback 2, I just haven't haven't gotten up the nerve to cut into the case yet.

Omega-TI Posted April 9, 2017 Share Posted April 9, 2017 Impressive! Did you use a Dremel? Quote Link to comment Share on other sites More sharing options...
Mr SQL Posted April 9, 2017 Share Posted April 9, 2017 That looks really cool! I thought the Flashback 2's were limited to 4K carts only due to a design flaw. Ms Pacman is an 8K bankswitched cart, so I bet the supercharger and the harmony would work with your model too. Quote Link to comment Share on other sites More sharing options...
SignGuy81 Posted April 9, 2017 Author Share Posted April 9, 2017 Impressive! Did you use a Dremel? Yes. I goofed and got a little too close to the corner of the case and scraped it a little. Isn't very noticeable even up close looking at it but the iphone gets everything. 1 Quote Link to comment Share on other sites More sharing options...

I can't find it now but I came across a page before browsing the web that listed games that were compatible and games that had issues but I can't find it now. 1 Quote Link to comment Share on other sites More sharing options...

Jinroh Posted April 12, 2017 Share Posted April 12, 2017 Awesome job looks so clean! I would love to mod my Flashback 2 similarly as well. Quote Link to comment Share on other sites More sharing options...
iesposta Posted April 12, 2017 Share Posted April 12, 2017 If I recall, the A12 line, which internally is handled correctly because it plays built-in Millipede (w/Sara chip RAM), is not working correctly when you solder a cart connector to the circuit board numbered traces. Games with RAM, advanced bank switch game carts, and The Supercharger fail because external A12 doesn't change. I tried my plain 32K bank switched Berzerk hack, and that runs on the Flashback 2. So any non-RAM 8K, 16K, 32K should play. I seem to recall some Undocumented Opcodes cause some game programs to fail, but those would be mostly used in homebrew era games. The Flashback 2 board needs probed to see if the A12 line can be picked up somewhere else. Like when playing the built-in Millipede, is an external trace changing the way A12 should? The Flashback 2+ has a ROM board with pins that hold the built-in games. Some of those pins have to connect to the "Atari on a Chip". The early Flachback 2 had the ROMs under a black glob. 4 Quote Link to comment Share on other sites More sharing options...
SignGuy81 Posted March 13, 2018 Author Share Posted March 13, 2018 I've been aiming to come back here and upload the STL files but never got around to it. I uploaded them here http://atariage.com/forums/topic/276533-wanted-cartridge-guide-and-cartridge-connector-for-2600/ in case anyone was interested in making some. 1 Quote Link to comment Share on other sites More sharing options...

I put one on mine, but not sure I did it correctly, as the output voltage reads 4.2V (maybe it always did). Carts + internal ROM still work though.

Crazy Climber Posted January 14, 2022 Share Posted January 14, 2022 I had one of these way back, can't remember what I did with it. Might be around here somewhere still... Quote Link to comment Share on other sites More sharing options...
jer10571 Posted January 28, 2022 Share Posted January 28, 2022 I've had a couple of Flashback 2's for quite a few years now with the intention to do one of these mods. Still trying to decide the location. I kind of like the idea of putting it on the right side. Still in the 'design' or 'Trying to figure it out' phase. So far I have everything I need except the the toggle switch. I think I will get another channel selector switch to use for that. Quote Link to comment Share on other sites More sharing options...
JimmyIpock Posted February 15, 2022 Share Posted February 15, 2022 I sell mod kits for this. With the switch integrated into the cartridge guide. Here: Quote Link to comment Share on other sites More sharing options...

Or just the top. 1 Quote Link to comment Share on other sites More sharing options...
JimmyIpock Posted March 2, 2022 Share Posted March 2, 2022 I sell these as kits, the kit includes a template that fits on top of the flash so you can mark where to cut. The cartridge slot with the leads pretinned, the switche(s) calibrated to activate when the cartridge is inserted. My website is here: www.flashback2.com If you'd like one, tell me the color you'd like (most choose black, but I can make about any color), Use paypal friends and family to send $35 to jipock@gmail.com and give me your address. Thanks! 1 Quote Link to comment Share on other sites More sharing options...
phattyboombatty Posted March 2, 2022 Share Posted March 2, 2022 @JimmyIpock I understand that the cartridge mod can be performed on the FB2+ as well. I find no mention of this on your site. Do you know if your mod instructions would be identical on a 2+? Quote Link to comment Share on other sites More sharing options...

However, if you would like for me to mod your FB+, I would be willing to take it. If I cannot mod it, I will find a really nice FB 2 and mod it for you. Normally it's around $50 to mod someone's Flashback for them. However, I would be happy to do it for the cost of the mod kit $35. That removes your risk. Of course, you can order a mod kit for $35 from me if you want to do the work yourself. 1 Quote Link to comment Share on other sites More sharing options...

First time I checked on this post or any for that matter for awhile but I say that is the nicest one I've seen online for top loader. I really like it.
