Re: emulator on pc screen "permi-etch"

Actually I know it as "screen burn-in". https://en.wikipedia.org/wiki/Screen_burn-in
There's example code on the gfa master disk or in Frank's book showing how to patch the editor colors.

Re: PFX packer

This should be obvious. It doesn't support the packing method. If the program can't identify the packing method, it's probably a custom packer someone made just to keep you from doing what you are trying to do. My experience has been this, if these multi-depack apps can't handle it, you are screwed ...

Re: GFA - Calling Zview to display a picture

Glad to help. You can use appl_find() to check if zview is already running. You only need the base filename and it must be padded to 8 characters with spaces. find$="ZVIEW" status&=APPL_FIND(LEFT$(find$+SPACE$(8),8)) TosWin2 has an option to write log file: Options -> Config console Se...

Re: GFA - Calling Zview to display a picture

It might be that shel_write() does not format the command line for you. Try this:

Code: Select all

file$="C:\PICTURE.TGA"
c$=CHR$(LEN(file$))+file$
~SHEL_WRITE(1,1,0,c$,"C:\ZVIEW\ZVIEW.APP")

Re: File that can not be deleted or renamed.

PureC has done this to me a couple of times leaving a file I can't delete under normal circumstances. The filename appeared blank. Oddly I was able to delete them from gfabasic with the KILL command.

If the palette split is interrupt driven, you can try disabling it before disk i/o, then re-enabling it after disk i/o. Just and idea. ;)

Re: guide to GEM coding with AHCC

GEM does not provide any sort of AES message when data arrives that needs processed. You end up having to use an evnt_multi() with the timer option and then polling the serial port from a timer subroutine. As for the bitmap buffering. From my own experience, GEM doesn't normally provide rendering to...

Re: "WTF?" issue - help

Devpac certainly has its quirks. I had it complain about the IIF directive being on the same line as a label in an include that never changes. However it compiled fine for months, then suddenly it's a problem. It's done this to me twice. Very bizarre.

You can disable individual optimizations, but looking thought the manual I don't see where it lists that specific optimization. You can always add to the source: OPT O- ;all optimizations off for test purposes
