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? noMRQ.mp4 Edited January 22, 2020 by oakcitycomics Quote Link to comment Share on other sites More sharing options...

Both mine are early K models (IBM) one from 1993 and one from March 94 Quote Link to comment Share on other sites More sharing options...
oakcitycomics Posted January 22, 2020 Author Share Posted January 22, 2020 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. Goodjag.mp4 Quote Link to comment Share on other sites More sharing options...

walter_J64bit Posted January 24, 2020 Share Posted January 24, 2020 (edited) Did anyone check to see if it's a "NTSC" or "PAL" problem with the game system? Edited January 24, 2020 by walter_J64bit Quote Link to comment Share on other sites More sharing options...
Rick Dangerous Posted January 24, 2020 Share Posted January 24, 2020 That is the first i've seen the Jad SD cart menu...looks freaking awesome. Cannot wait to get my hands on one of these.. 1 Quote Link to comment Share on other sites More sharing options...

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.

neo_rg Posted January 27, 2020 Share Posted January 27, 2020 The working Doom rom when testing the jagGD cart had a crc32 checksum of 5e2cdbc0. Quote Link to comment Share on other sites More sharing options...
oakcitycomics Posted January 27, 2020 Author Share Posted January 27, 2020 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 Quote Link to comment Share on other sites More sharing options...

oakcitycomics Posted February 1, 2020 Author Share Posted February 1, 2020 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 Quote Link to comment Share on other sites More sharing options...

SainT Posted April 10, 2020 Share Posted April 10, 2020 Sorry, very late to this one, but that's really interesting that the difference is having an existing E2P file. That's the EEPROM save game info (which I'm sure you know!), which doesn't actually affect the way the cart behaves (EEPROM is always enabled), however a save game will naturally affect the game code . I've done some patches relating to instability on loading with very old 1.0 revision GPU and DSP, this may possibly have a knock on with EEPROM data as its using the same cycle access times as other IO. I'll PM you a firmware update to try out, it would be very interesting to see if it helps with this. 2 Quote Link to comment Share on other sites More sharing options...
