    sorry the video is a bit out of sync and I chose a game that takes a little while to boot
    Debug options are only for comms port users, my AR does not have a comms port so this is not tested by me

    Extra Notes:...

    I have noticed a bit of intermittent lag in some FMV's this may just be a CD drive issue though, I would need to test with a swap trick or mod chip to verify that

    I have also noticed though only via an Atlus homebrew disc so far that PSEUDO does not let the Atlus disc boot another Saturn program from it as it should, it just returns you to Saturn bios if you try

    The Croc - Legend of the Gobbos (US) issues are also there for the retail version, normally to solve this you just boot the console first then insert the disc at the bios screen, this does not work for Pseudo Saturn though

    PSEUDO SATURN features wish list:...
    Most of this is planned anyway

    Save data storage
    Save data storage that acts like a Saturn Backup Memory (another words it can be accessed directly by games)
    Cheats
    Improved compatibility (This is almost perfect as it is, though plenty of games left to test still)

    Updated Compat list, this is going to be the last update for a little while as I ran out of CD-R's :/ but I will get back to it once I get some more CD-R's

    For now I'm enjoying Shining Force III (again), after playing through that I will get back on top of some of my uploads and back to this when I get the CD-R's

    Only 3 games that have major issues and Croc that seems to glitch, but that is the same with the retail copy only the fix used with the retail version I can't seem to get working with this mod :/ so I guess that is 4 games

    This looks really good I have been using the swap method for years with no faults but this looks too easy to not want to drop $25 for a action replay.
    Best thing about something like this is it really isnt hurting the developer because when was the last time they re-released any saturn game?

    I did see this a few weeks back on assembler but now that they fixed the patching issue i dont need to reburn disks i am sold Thanks for the heads up.

    this sounds interesting now I just need to get an action replay cart.... and a sega saturn to give it a try, emulators are fine but it's bugging me somes games that are not playable so the solution is the real console.

    What games are you talking about... create a new thread in the emulation section if you like, I can get most games working fine via emulation, I just like the real thing more

    When you say "Great news games no longer require patching" on the new installer, it means that the PSEUDO SATURN does not need to be in the game image downloaded? Can it be directly written to CD?

    correct, you can burn the disc image of saturn games directly no patching needed.

    Just chiming in to say if anyone’s having installation problems and/or suspects they’ve bricked their cartridge, don’t worry, just grab the Atlas installer Zorlon posted above. I had a hell of a time trying to get the mod working on an Action Replay 4M Plus. Post write verification failed and bricked the cart each time with the official installer. I tried a few different installers and had similar results, but the only one that worked reliably for me and brought it back to life was Atlas. Skip the others and use that one if you have a 4M Plus.

    I can't get my Saturn to recognize the Atlas disc at all. It reads burns games via swap disk fine, but it will not read the Atlas disc to flash the cart at all. I suspect it has something to do with my CD burners. Tried it on three different drives, Windows and Mac, all three could not burn at less than 8x speed. I read that it needs to be burned at single speed for the Saturn to read it. Any ideas what I can do? Anyone willing to send me a working Atlas disc if I cover postage?

    where did you read about the burning speed

    burning at the lowest possible speed is enough be that 8x or in my case this was 10x Imgurn set at x1 should do the trick with DAO/SAO write type (if you set that to 1x all it does is auto select the slowest possible burning speed for your hardware) TAO write type can cause all sorts of issues

    try the more simple single swap trick, i.e. start with a retail disc then swap to the CD-R, basically you skip the first swap totally and just do the swap at the same place you would normally do the second swap, or if your using the action Replay 4M plus then you just boot with your retail disc in then at the main menu of AR4M+ you swap the disc for the CD-R and hit start game

    this does need to be on a CD-R though, CD-RW will not work

    Hey Zorlon, I'm in business! Thank you so much for your suggestions. I was finally able to get it to boot using the single swap method. I also switched media from Phillips to Memorex CD-Rs and it booted literally the first time I did the swap. Before your post, I made like 30 coasters. Thanks again!
