JOY.EXT Bővítő / Extension
« on: 2021.January.04. 23:51:21 »
Megtaláltam a Joy.ext bővítőt. Betöltöttem az Enterprise-ba, és látszik hogy ott van (lásd csatolmányt), de nem tudom használni.

Itt egy nagyon rövid leírás, a "Joy.ext"-re kell rákeresni: http://www.ep128.hu/Ep_Util/Util.htm

Itt a letölthető fájl: https://enterpriseforever.com/letoltesek-downloads/egyeb-misc/?action=dlattach;attach=399

Van valakinek valami tippje, hogyan lehet használni a bővítőt?

=English version=

I found recently the "Joy.ext" extension. I loaded to my Enterprise, I could see the extension, but I was not able to use.

The short hungarian description is here, use search on page with expression "Joy.ext": http://www.ep128.hu/Ep_Util/Util.htm

The downloadable file is here: https://enterpriseforever.com/letoltesek-downloads/egyeb-misc/?action=dlattach;attach=399

Does anyone have a clue, how to use that extension?

I was playing with it some time ago. It is a hack for the original EXOS drivers, not for the Language Rom ones.

Try to load it without the cartridge, as it is an extension it will load from the WP pressing the F8 key and typing "load joy.ext"+Enter.

As you only use the Tape: device, to load the extension press F1 and type joy.ext+Enter. EXOS will detect that it is an extension header and will load accordingly.

You mean the problem maybe, that I am using a german (brd) basic cartridge?

Igen, tényleg csak angol géppel működik. Gondolom nem EXOS kompatibilis módon, közvetlenül ír bele a rendszerszegmensbe, csak éppen hiába ír az angol billentyűzet kezelő területébe, ha az nem aktív.

Lehetséges lenne valahogy kijavítani, hogy német gépen is működjön? Sok dolgot kellene átírni a kódban?

Is it possible somehow fixing the code, which makes it working on german computers as well? Is there much code to change in the file?

It is a hack, not a real driver. The Language Roms use a different keyboard driver on other memory zone, but also the zone is not used the same...

On the other side, not very useful, because games don't use the keyboard driver, they scan the hardware directly.

To do something similar, I would search on the Rom the keyboard call from the Editor driver, then instead of asking the status of the internal joystick, change it on the Rom, only one byte, a 0 by a 1 or a 2. But hacking a Rom is definitive on the real EP, not a simple software in Ram....

Enterprise Technical Information EXOS 2.1. You may find it in the Hungarian translated version (EXOS 2.1 Változat Műszaki Leírás); at pg. 208-209.
