    Thanks for the reply guys. I'm only passing on my observations and adjusting the pot appears to change something with the motor but I could def be wrong in what is actually happening. The motor will spin at what appears/sounds like 42x CD-ROM speeds if I turn it too far in one direction, I'll make a video to demonstrate. Maybe there is another pot somewhere else on the transport?

     

    All the games I'm testing are originals except World Tour Racing but it won't read that one either. It's definitely a frustrating issue since it plays music CD's and some games without issue and my original game CD's are in great condition.

    I recently picked up a broken Jaguar CD on Ebay and it's not able to play all Jaguar CD games. After a few repairs Highlander and Dragon Slayer fire right up no issue. I Can also play music CD's no issue. Unfortunately the best games like BattleMorph and Iron Soldier 2 refuse to start. The unit spins up the CD and appears to be trying to load the game for about 30 seconds before it fails and gives the disc missing error. I've tested these games in another JAgCD unit I have so I know they work.

     

    So far I've replaced the laser transport and all the caps. I actually even swapped in the original laser and have the same results after I discovered adjusting the POT on the transport will get the motor/spindle turning. I'm not entirely sure the POT adjusts anything on the laser, I think it actually adjusts the pulse signal going to the motor. If you turn the POT too far one way it will prevent the motor from spinning, if you go too far the other way the motor will spin way too fast when it attempts to reverse direction to slow the CD. I've also noticed the two voltage regulators(I think that's what the are, they have fins/heatsinks attached) seem to get hotter than I think would be acceptable for a consumer device. Does anyone have any ideas on what to try next? Thanks everyone!

    Anyone with a Skunkboard and Pro Controller interested in trying out my Pro Controller support for Doom?

     

    I've added:

    • Independent left and right strafing on shoulder buttons.
    • Circle strafing is much easier to perform.
    • Weapon selection on the x and y buttons.

     

    Grab the file here:
    https://drive.google.com/…/1yt9anfi9gXNXB4SuHlxgi0bSZ…/view…

     

    With the Skunkboard, you need to upload the original Jag Doom rom to flash (jcp -f "rom file") and then reset the Jag (jcp -r) and then upload this to memory (jcp doom.abs).

     

    Much thanks to Carl Forhan for all the support I needed to get this going!

    As expected, something really silly, I just needed to correct a path in the makefile to match my environment.

     

    C2OBJ = gcc -B/prog/jaguar/bin/ -b m68k -V2.6 -Wall -DJAGUAR -O2 -c -o [email protected] $?

     

    to this

     

    C2OBJ = gcc -B/jaguar/bin/ -b m68k -V2.6 -Wall -DJAGUAR -O2 -c -o [email protected] $?

     

    And now I have a doom.abs file!

     

    Will the ABS and WAD file fire up in an emulator? Trying to determine if I can use an emulator to quickly test my changes.

    I think the NUON is def one system that will also look better on CRT. I believe it outputs games at 480i, apparently a difficult resolution to upscale, but the internal frame buffer/native resolution is lower for games. I have a suspicion that Iron Soldier 3 is running at a lower resolution than either of the Iron Soldier games on the Jaguar. Either way, neither my XRGB Framemeister or OSSC produce a satisfying image on my 1080p OLED when using the component video output from an N501. I really wish I had a PVM to connect my NUON to, I remember T3K looking great on an old 27" Sony Wega CRT.

    Sounds like it might be a fault of your dev tools - are you sure they're ok?

     

    Apologies for the delayed response guys. I've been spending most of the past few weeks in the NICU with my newborn. I def appreciate everyone's responses.

     

    I've tried emulating every CPU available in DOS box.

     

    It very well could be my dev tools, although I'm using the files Carl sent me. Is there a guide for how to setup from scratch?

    Thanks for the info Tursi, I've tried several CPU cores and types, also adjusting cycles. When it crashes I get the following error "Exit to error: IRET:Illegal descriptor type 12" in the DOSbox status window. Maybe someone can share their DOSbox config?
