Oxford Trivia corrupt cart fix, Pascal?
Posted: Tue Aug 09, 2022 5:51 pm
I thought I'd put this out here in case anyone with a lot more knowledge than me is able to fix this issue or offer some guidance.
I have an original copy of Oxford Trivia by Talent. There are 2 cartridges, one for the game and one for the questions. Both have corruption but the corruption to the questions cartridge is probably not terminal as it only affects 4 files that appear to be question and answer sets - the other categories are ok, so probably work.
The corruption to the main game cartridge is more severe, it has the following damaged files:
GRAPHICS
TRIV_3g_PEXE
The latter is the main exe file for the game.
I got copies of both those files from Rich. Both are the same size as the corrupt files my the original dump of the cart so I thought I may be able to copy the good files over the corrupt ones in the mdv dump, which I think has worked for the GRAPHICS file, but something else goes wrong and when it attempts to load it illuminates all of the mdv lights (in qemulator) and locks up. There is some kind of copy protection as the instructions state that it requires the original to be in mdv1_. I thought that having good files on an original dump image of the cartridge might fix it (it has for other games) but no, perhaps it checks something else and me copying a good file over a bad one has destroyed whatever its looking for.
To run, it requires the game cart in mdv1_ and the questions cart in mdv2_.
A (windows) zip is attached which contains:
Oxford Game Original.mdv - the original dump made using mdump_task from Danile Terdina
Oxford Game Patched.mdv - original dump with files GRAPHICS and TRIV_3g_PEXE copied over the corrupt originals
Oxford Questions Original.mdv - original dump of the questions cartridge, which has corruption to MUSIC, SPORT, HISTORY and CINEMA.
OxfordTrivia1.mdv - The version of the Game cart supplied by RWAP that contains all good files but doesn't work either.
OxfordTrivia2.mdv - The version of the Questions cart supplied by RWAP that contains all good files.
While trying various things I did at one stage get the following Pascal error: This is the screen from dumping with mdump_task. Could there be 2 deliberate missing sectors that are something to do with the copy protection? Just a wild guess, I have no idea, but me copying a good file over the corrupt one would, I assume, change those missing sectors? (As this is broken and is useless as is, I saw no potential issue with copyright infringement)
