Doom error

Delete the MRQ. It might have the wrong EEPROM type.

Deleting the MRQ didn't change anything. Still if I start a game with a previous .e2p I can reliably get it to crash more then half of the time. If I start a game with no .e2p in the folder I've been unable to get the game to crash.

 

Firmware v1.07 Menu v1.04 ASIC v1.05 and Stub V1.02 are the current versions correct?

Does this make it an M model? It's a UK one

Yep that's an M by Comptronix or something like that. Both mine are early K models (IBM) one from 1993 and one from March 94

Here is a video of it crashing using the Goodjag 2.01 rom.  Just crashes to a black scree no rainbow bars but still crashes with using a .e2p from a previous game. I'm at a loss at this point. Maybe its just a bug in the early Jaguar silicon not playing nice. I'm not ruling out the possibility both my Jaguars could be the culprit since they are both early IBM models. Who really knows to be honest. I did order another Jaguar console, hopefully it will be here early next week.

Yes same versions as me. Its been running for 2 hours here in demo and I started a game on lv3, no issues.

 

Tried a different SD card?

Yep 16gb PNY, 16gb Silicon Power, 32gb Transend, 32gb Samsung, 64GB Sandisk, 128GB Sandisk, 200GB Sandisk, and a 4gb one that came with my Nintendo 3ds when I bought it new

Did anyone check to see if it's a "NTSC" or "PAL" problem with the game system?

Both of my systems are NTSC North American release both purchased originally from Babbages. As far as I know the two Doom roms I've tried are region free, could be wrong.  I just find it odd this behavior does not happen with a retail doom cart. The M model Jag I ordered off ebay shipped yesterday so hopefully it will be here early next week. I wish I still had my Skunkboard to test it as well but sold it once I got the Jag SD. Though I don't remember every playing doom on the skunk since I had a retail cart.

I thinking maybe adding a 50/60 hz mod to your Jag to see if having your Jag in PAL would make a differences.

What is the checksum on your Doom ROM?

 

Mitch

MD5 Checksum for the two Doom Roms I've used

Doom (World).rom = 3A5878EA3F391174BECC37B037318804

GoodJag 2.01 Doom - Evil Unleashed (1994).jag = 3A5878EA3F391174BECC37B037318804

I'm using a program called Checksum Calculator and its producing this value with the two roms I've got both the same. I'm using the GoodJag v2.01 rom set which was the one Saint recommended in the main forum and the Jag (World) rom set.

 

Doom (world) =1579998144

GoodJag 2.01 Doom - Evil Unleashed (1994).jag =  1579998144

 

They look to be the same rom. I downloaded 3 other rom versions of doom off the internet all the same checksum as above. I'm not finding any rom with 5e2cdbc0 . Not sure if its Checksum Calculator that's producing a different value or if that rom isn't the main on flooding the internet cause I'm not able to locate any that doesn't produce the value 1579998144

My M model Jaguar arrived yesterday and playtesting it has no issues with Doom on Jaguar SD. Still not totally sure it was my two K early model Jaguars since they did not display the issue with a retail Jaguar Doom cart. Has anyone with a K model Jaguar with the Toshiba chips manufactured before March 94 tested

It may be the SD card in that one situation with Doom on K model Jags. 

Anything is possible, it could be the sd or current firmware or even my two K jaguars are finicky. Everything works great as far as I can tell with the M model I picked up off ebay so I'm happy regardless
