This is the first version of SAM2_ZX81 to support hires and pseudo-hires ZX81 programs by Johan Koelman.
After booting (F9) the emulator it came up waiting for a key press. Once done, you are in the ZX81 mode. To load a program simply type in:
LOAD “1” (if you are on SimCoupe or on floppy disk with a real SAM) or
LOAD “2” (if you will load from SAMs harddisk)
A menu will be displayed, showing you all the programs to load.
Note: When a program is loaded, it will not autostart.
When you see 0/0 in the upper part of screen, simply type RUN and voila, you see a HiRes Zeddy game emulated on a SAM. Except “Micmouse”, type in GOTO 5 to start.
Even it is the alpha version, Johan has build in some extra keysettings:
F1 - shows you a help screen:
Press F1 again to return to the main program.
Press when help screen is shown:
F2 - for more or less screen refreshs
F3 - for more or less counted clock interrupts
These options can be very helpful on pseudo and hires games. The changes are not shown, this might be added later!
To exit a program pess TAB and ESCAPE together.
- Madjump II
- Flater en Flaters (Guus-Fla)
- Micromouse goes debugging
The ‘SAM2_ZX81’ can also load normal ZX81 programs, as I have tested several times.
