There is no uef tape copy of this at STH to check to see if this was caused by the disc hack or not.
I'd hazard a guess that the answer to this conundrum is a resounding yes! :lol:

Re: Disc Doctor interference

Lee has reported that on a real BBC with Datacentre, there is some fast flicker on the robot on the second screen ( I believe it is the robot's eye that flashes red and yellow). Indeed I had not noticed as my test setup had Disc Doctor in slot 13 (which poked &0D to &130). Loading it into slot 0 (t...

Re: Genie/Genie Junior by PMS

For the the 1.02 looks good. I fixed the changes I made within emulator (my biggest problem was that I had forgotten to 'format' the Genie). Now, both look good to me. I think that was my thinking behind the following #-o :roll: If you think it might help, it would be trivial to dump the (battery b...

Re: Disc Doctor interference

IIRC the reason why I did not to use the BFMOF disc version was because BITD the tape version was protected but a disc hack of it was given to me and that is what was used. When I came to remaster the games a few years back, I found a disc version on STH but it had extra files that loaded a master ...

Re: Genie/Genie Junior by PMS - clean ROM dumps

With the help of Colin Cameron (son of the one of the founders of PMS). We got a clean dump from the original ROMs for BBC Genie. I've tested it (under emulation) on BBC B and BBC B+ and it works fine, however so far no luck on Master 128. I'll see if we can find a different version for that one. I...

Re: Disc Doctor interference

Another one to cross off my list is By Fair Means Or Foul. This is the same game as Pro Boxing and the tape version of that loads with Disc Doctor. The Disc Version of BFMOF loads the game at &400 and not &100 like mine. Changing my code to run from &400 cures the problem. Then why not just use the...

Re: The Magic Telephone (aka "The Magic Telephone Box")

Found this a while ago, but never compared with the version here. Disk attached doesn't ask for a 4 digit code (i'm not sure how that's used by the program), but instead runs I.MAGICT, which installs an interrupt driven routine. Also contains some saved games, although 2 appear to be at the start (M...

Re: Disc Doctor interference

DISC DOCTOR 1.09 is what I used. Also, It was my code that Cyborg Warriors did not detect, that was the checking &130 for &0D or anything other than 0 that I removed. Not the ROMOFF code that works for Atic Atac. I see. So the 2nd, uppercase ROM header checker is probably redundant! I would've thou...

Re: Disc Doctor interference

Just one last question. Would it work on a BBC with a Datacentre where Disc Doctor may be stored differently? Since the code is only disabling the ROM with the matching header "DISC DOC" from within the paged ROM table I can't see why it shouldn't. And stored differently how? If the name is differe...

Re: Disc Doctor interference

Early tests from Lee show that these games mainly crash or fail on a real BBC with Datacentre and Disc Doctor, so the fix isn't really viable and the "Remove Disc Doctor" message may be the best way to go where needed. I don't think there's any reason that disabling of installed ROMs would be causi...

Since there are many different ROMs that can interfere with many different games, I found that the best practice on my disks BITD was to have a program running from !BOOT, before the menu of multiple games that *ROMOFF''d (from BROM) all of the unnecessary ROMs so that there was no problems with com...

If you think it might help, it would be trivial to dump the (battery backed) RAM sections, just after resetting the device, in case the ROM code is looking for something specific?

I appear to have a Beebugsoft software demonstration disk somewhere and it mentions Studio 8.

It also plays a version of Eleanor Rigby by the Beatles. All in glorious MODE 7 block graphics.

Anyone else have this? I can hopefully find a copy if anyone wants one.

Re: Watford Electronics Diagnostic Disc question

Ran option D from this disk image on BeebEm 4.14 and the random access test writes from absolute sector &18F (track 39 sector 9) down to &002 (track 0 sector 2) with the values of 0 to 255 in each sector then reads them back.
I would hazard a guess that it's a DFS incompatibility?
