VESA modes technical question

[Antoni Gual]

This how I modified Tclib15's Pset24 sub:

Code:

SUB Pset24 (x%, y%)
' Plots a pixel using the current RGB combination

'DEF SEG = &HA000
IF x% < 0 OR x% >= ScrWidth THEN EXIT SUB
IF y% < 0 OR y% >= Scrheight THEN EXIT SUB
Offsetb& = (ScrWidth * y% + x%) * Bpp

bankb& = Offsetb& \ 65536
Offsetb& = Offsetb& MOD 65536

IF bankb& <> curbank THEN
  curbank = bankb&
  Regs.ax = &H4F05
  Regs.bx = 0
  Regs.dx = bankb&
  CALL INTERRUPT(&H10, Regs, Regs)
END IF

POKE Offsetb&, blue%

IF Offsetb& = &HFFFF THEN
  Offsetb& = -1
  curbank = curbank + 1
  Regs.ax = &H4F05
  Regs.bx = 0
  Regs.dx = curbank
  CALL INTERRUPT(&H10, Regs, Regs)
END IF
POKE Offsetb& + 1, green%

IF Offsetb& = &HFFFE THEN
  Offsetb& = -2
  curbank = curbank + 1
  Regs.ax = &H4F05
  Regs.bx = 0
  Regs.dx = curbank
  CALL INTERRUPT(&H10, Regs, Regs)
END IF
POKE Offsetb& + 2, red%

END SUB

It works for me, but i have a 32 bit card...

You could also try to set up a suitable line length. It would not increase speed in YOUR computer, but it would do it in many others.
