While checking the Spectrum TAP Games from the TOSEC Set to build a RomVault Dat, i was suprised that so many Games
wont run on the MiST (around 30%). And i discovered a curious Bug. Plenty of Games print on the Screen "Spectrum Play" instead of a character.
The ZX Spectrum does not have Hardware Sprites, usualy the Game modifies the Character Set and use this character as a software sprite. But the Spectrum also has Basic Keywords in his Character Set (Example: Print chr$ 254 would print "RETURN" on the Screen).
If you take a closer look at the beginning of the Game "Androide (1984)(ERE Informatique)(fr)[16K]" from the Tosec Set, which is a pacman clone, you see that pacman char is hunted from 4 times the word "Spectrum" rather than the 4 Ghosts !
The Spectrum Char Set does not have the Words SPECTRUM or PLAY in it, so where did they come from ?
First i checked the TAP Games on a Spectrum Emulator and they all work fine. But not only Sorgeligs Core is affected, also the very first ported Spectrum Core from Mike Stirling has this strange behaviour with the same games in CSW.
I checked then the Char Set with a little Basic Programm (10 FOR a=32 TO 255: PRINT CHRS a;: NEXT a) and did RUN it but everything was normal. So i can only think of a Bug in the z80 or in the spectrum.rom
Some examples of affected Games:
A.T.F. (1988)(Digital Integration)
Academial Patience (19xx)(Tiger's Claw)
Alcatraz Harry 2 - The Doomsday Mission (1984)(Scorpio Gamesworld)
Androide (1984)(ERE Informatique)(fr)[16K]
Angler (1983)(Virgin Games)
Animated Strip Poker (1985)(Knightsoft)[a]
Antteroo the Mutant (1985)(Central Solutions)
Apocalypse (1983)(Red Shift)
Can someone please check a few of the listed Games on a ZX Uno ? I ordered one but it will take some time til i have it.
