Executing a basic program as a binary is pretty easy... (once you know
about the onerr flag anyway)
; Clear onErr flag
LDA #$00
STA $d8
; Store start of basic program (e.g. $801)
LDA #$01
STA $67
LDA #$08
STA $68
; Store end of basic program (start + filesize -- e.g. $6000)
LDA #$00
STA $AF
LDA #$60
STA $B0
;Set LOMEM (optional?)
LDA #$00
STA $69
LDA #$80
STA $69
;Set HIMEM (optional?)
LDA #$ff
STA $69
LDA #$af
STA $69
;Start the basic program
JMP $d566

So you could shove this loader somewhere low in memory like $300 or
you could pre-pend it to the beginning of the basic file.  This is
exactly what I use for AGS to execute basic programs and it seems to
work pretty well.  I set LOMEM to START+SIZE+1 and HIMEM to DOS -1
(and if you don't care about DOS, then just DFFF).   I have a feeling
that what you're doing probably doesn't matter too much if LOMEM or
HIMEM are set -- but I could be mistaken.

Holy cow, goodness no.  There's over 256 of those things, and many
gems among them.  I'd be hard-pressed to complain without feeling like
a total jerk for doing so.  ;-)

Any chance you're willing to share that?  ;-)  I could use something
like that to speed up the AGS menu...

By the way, thank you! :-D
