I mentioned that above. The burned cd works in yabause too. I think it's a laser issue. I even had a spare laser and swapped that in but that thing didnt work at all. At any rate, I ended up ordering a fenrir cuz i think it's time to go ODE in this ol saturn. All that is to say, none of...

Hey @slinga - I've migrated from the SGEX thread to here now. I'm at the final steps, having a similar problem to what Tracker_TD was reporting. I compiled a SGC iso using Jo Engine. I tested it in a couple emulators, running the Jo Engine scripts, and my Castlevania SOTN save game shows up...

Revising this post, cuz I got it working. Didn't realize you have to keep letting the data "play" after the initial sound burst. Finally figured that out, and success! Also, a separate tidbit for anyone doing this in Cygwin - the boxes have to be unchecked in Windows Sound, for the line in...

So I had some success on a windows 7 machine, with cygwin. Same test failures from make check in that environment, but the test message was received by minimodem. I then tried capturing a save file, and kept getting the NOCARRIER message like Mobius reported. I setup a usb debian drive, was...

Sorry for reviving a fairly old thread, but I'm having difficulty getting minimodem work. I'm not super savvy in linux environments, so probably doing something dumb that somebody more knowledgeable can point right to and know where my error is. I have cygwin and minimodem running on my...

I had tried every damn trick in the book....many many times, with this Saturn. I was tired of screwing with it, and getting marginal if any results. I figured the same time could be invested in a permanent fix. That's just me tho, :) but yes, I tried every trick - lift it out part way, wedge...

Here's a line diagram, including only the necessary connections/contacts that need to be wired, the AR contact numbering scheme used at the refence link, and the motherboard solder joint numbering scheme printed on the board (also corroborated with the schematic posted above). Hopefully this is...

You and me both. This effort took almost a full week, starting on a Sunday and consuming nearly every waking minute after work (often staying up much later than I should have). :hungover: Hopefully it is useful for others. While the Rhea/Phoebe solution is pretty awesome, and the currently...

Separate thread updated, and I'm happy to report that the hard-wired cart is flashed with Pseudo Saturn Kai Lite and the mod is complete. Thanks all for the help and thank you vbt for this great tool!

Well, putting a simple "break" switch on pin A45 seems to have done the trick. Setting the switch to "off" disables the cart and the Saturn operates as if no cart is inserted. Setting the switch to "on", the Saturn operates with full cart functionality. Nonetheless, I linked your post in the...

Found the equivalent pin on NTSC Saturn - it's pin A45. Desoldered it, and the cart is disabled. :D

Lastly, a picture of the solder side of the AR PCB, as requested by cafe-alpha:

cafe-alpha, I started a new thread so as not to hijack this one: https://segaxtreme.net/threads/permanent-cart-slot-fix-hard-wiring.24243/ the picture of the solder side of the PCB is there. I desoldered the contact at the PCB that corresponds with A47, and it didn't seem to have any effect...

Item #3 requires successful achievement of #4. All 5V lines desoldered from hard-wired cart (8 total), resulting in Saturn booting normally (not into Action Replay operation), but with extended memory (1MB/4M). I also determined in the process that the hard-wired AR cart would continue to boot...

Item #1 and #2 completed successfully.

Continuing this from the Psuedo Saturn Kai thread, so as to not hijack that thread. The ultimate goal of this project is to: 1) Delete the failed cart connector 2) Hard-wire a AR 4M Plus cart to Saturn motherboard 3) Flash AR cart with Pseudo Saturn Kai, for ultimate saturn gaming...

Oh and to seal1, my cart slot stopped working. Couldn't get the cart to read, couldn't flash it. Through some pretty extensive discovery during the whole process, I found that even when the cart wouldn' boot due to this or that wiring issue that was yet to be resolved, the extended memory...

Nice, great info! I was also pursuing how to disable the hard wired cart both as a matter of general functionality and as a matter of being able to do the swap trick. I desoldered all 5v lines except the ones at pins 0 (according to the numbering at the below link)...

Wondering, is it possible to flash a AR 4M Plus by directly programming one of the chips that is contained on the PCB via a programmer? I hard-wired in an AR 4M Plus, due to cart slot failing, and would like to flash it to Pseudo Saturn Kai...but swap trick is no longer an option and I'd like...
