Today fellow user retro-enthousiast DK Shadow reached out and offered a rarity: a floppy image of the official Amstrad Diagnostic Tools for the PC6486SX, PC7286 and PC7386SX systems (last system is of importance since it's what the Mega PC is based on). This was a floppy given to technicians along …

I'm sure you should be able to find a copy, or a copy by just googling for it... Then again, I'm focussed on HP200LX portables which have CGA so I can't test any of the sierra VGA only games... Yes, had a look on a popular auction site this morning and I've located a copy - just have to wait for it …

That's great :) It works on all old PC systems now :) We'll look into the remaining issue with the driver name and the install program, and hopefully peter from serdaco can get that fixed and check in a final, %100 version of this driver... Thanks again for helping to test the driver on a 8086 and …

Very interested to find out if it's the same result on a pure 8086 CPU :) Looking forward to it :) Well spurred on by the success of the V30, I worked late into the night to get the PC5086 back together and do some testing. I can confirm it works on all of the previous games I tested (obviously …

Can you open the resource.cfg file in a text editor and manually change the driver in there ? Hi Terrence, I can confirm it works after manually editing the resource.cfg ! - I've tried it on Space Quest 3, Laura Bow 1: The Colonel's Bequest and Codename Iceman - all three of these work with the …

Unfortunately I need someone with an S2P to test this... :( I'm hoping someone who owns one will see this thread and make a post offering help to test the fixed driver on a 8086/8088 machine... 😊 I have a S2P and willing to test. I have a Amstrad PC3086 with a NEC V30 fitted and an Amstrad PC5086 …

after that Popful Mail would not load. I had to delete the sram save file it created so the game would load but after a couple of times it failed again with a black screen - not even CD BIOS would load. Re-wrote the game files to SD again (there was no corruption but I did it anyways) but that did …

......the only thing that was the same in all versions were the small graphics glitches, Zalog can you test your system and see if you get this Tails corruption on Sonic 2? Yes have just checked Sonic2 and I get graphical glitches with tail too - I'd never loaded this game on the everdrive pro so …
