UnLock Software*SOLVED*
UnLock Software*SOLVED*
Hi,
ZX software that auto-runs, after loading, has more of a chance to fail.
Q: Can auto-run code be unlocked in some way, so only the binary gets installed without it being launched

Re: UnLock Software
On VB81, press the "Esc" key… it's an ASM exit key, to list the ASM code.
On a true ZX81, you had to poke something before loading.
Don't remember… it had to read my docs….

Re: UnLock Software
If you have a ZXpand, you can load the software with LOAD “SOFTWARE STOP ”, where STOP is a keyword. ZXpand emulation is available on EightyOne as well.
If you have real hardware with tape loading, I’ve read you can load with RAND USR 836 to stop auto-run. (This I’ve never tried myself.)

This ZXpand manual has NO dialog on adding ' STOP ', when LOADing:

What's your reference?

Re: UnLock Software
I don’t think you can break into my 1K games.
Simply because (especially the latest) the games don’t make a listing in BASIC.

Re: UnLock Software
mrtinb,
ZXpand did the job, thx!
Now, the attached >16K file ZXpand SAVEd, will not LOAD via EO tape, only ZXpand CAT.
What's the trick to get EO tape/wav to LOAD it, as well

Re: UnLock Software
In fact, two 'P' files can be generated from a tape.* how many P standards exist *
-1) The standard 'P" file from "Xtender": it's the memory snap from $4009/16393 (Version tag) to the Vars top.
-2) The second format (the pur format) is a 'p" file with the name header, generated with SAVE"HELLOWORLD" command.
(the "81" extension)
Emulators use to rename "81" to "P" files, and trim the name header "MYPROGNAMe"+"P file"... and ignore its name. The name will be the DOS name.
'81' format: NAMe+RAM SNAP (Pure tape signal)
'P' format : RAM memory dump.
