|Summary||07083: specpl3e: Certain working disks in older releases won't run|
Recent changes in disk emulation have broken some games. Golden Axe is now unplayable and was running fine in older versions.
Very possibly related to 07081.
|Steps To Reproduce||
1-Grab disk image (GoldenAxe(MCMSoftwareS.A.).dsk.zip) from http://www.worldofspectrum.org/infoseekid.cgi?id=0002081
2-Run the machine and press enter when Load is selected
3-Choose one and two player controls
4-Turn disk into side b
5-Start 1 player game, you'll see garbage in the game, you are able to move your character, but no more

|Golden Axe seems to run fine, without garbage. Batman and Robocop still fail to load.|

Hmm, I do not think those games ever worked (at least those versions).
Robocop has a 'Speedlock +3' protection system. Same for Out Run (MT 06957) and others.
That means 'weak sectors' so we are out of lucky.
Batman-TheMovie has a 'Paul Ownen' protection system. Same for Chase H.Q. and others Ocean releases.
AFAICR, that means that program tries to read higher sectors than EOT (end of track).
Maybe fixable, I will take a look (I think that others emulators just ignore EOT but it is a not good solution for MAME).

|Yes my fault, you're right. Those games never worked. I think I should use a .tzx image or maybe some other .dsk, like a compilation pack that time. For me this report could be closed since the main problem (golden axe disk) is playable again.|
