Leo> No I meant four pokes. Separate vpoke's are still slow.

leo, try to paste you source here, maybe we can suggest some trick to improve the speed

yep, remember it is a quick trial , normally i would code .rom in pure asm , what is nice here is that i could quickly get a decent speed with smal effort.
after that more effort , more time , more speed , but i am unsure to have that time .....
so rewriting very slow basic command in asm is ok but then changing all the structure to have an array for sprite update , then it is better to recode
from scratch in asm a kind of .rom then it is like cooking a msxdev entry ....

i can put a.dsk image here :
http://iledefra01.free.fr/msx/tdef.dsk

there are 3 files :
run"td1" is long like several minutes and generates the "td-g.sc4" with data in VRAM for sprite , board , crappy gfx, and trial trajectory for monster
then
run"tdef" launch the game
you can run directly "tdef" since "td-g.sc4" is already generated. some can generate other gfx , i include the td1 just if some wants to generate
other gfx of level with different monster trajectory.
enjoy !

i tried save "tdef",a in blue msx in a mounted dir but apparently i can only read from a mounted win7 dir ....

Nothing really good improvements comes to mind when I look this source. This is very good written BASIC.

Here are my 5 cents:

ADD:
10 DEFINT A-Z
... and remove all the "%" signs with search & replace.
This saves some space that is now used to store the source (and makes the source more readable, if you ask me)

ADD:
132 DIM SX(8),SY(8)
133 FORI=0TO2:SX(I+2)=8:SY(I+4)=8:SX(I+6)=-8:SY(I)=-8:NEXTI:SWAP SY(0),SY(8)

Replace lines 450-490 with
450 A=STICK(0):cX=cX+SX(A):cY=cY+SY(A)

This gives better controls.

And now with lives count bar on the right of the board, each ennemies that make it path to the bottom of the screen decreses your lives:

You didn't copy correctly. You still have only 4-way controls.

Ps. Instead of writing:
140 DIM X(12):DIM Y(12):DIM T(12):DIM TX(6):DIM TY(6):DIM SJ(6)

... you can just write:
140 DIMX(12),Y(12),T(12),TX(6),TY(6),SJ(6)

(Yes, I know... who cares)
They should! This kind of thing can cross that brittle little line between the dreaded "Out Of Memory" and a working program. A lot of small ones make a big one.

I think there are some thousand lines to go before "Out Of Memory" Then you can start removing those extra spaces between commands. (Yes, I tend to write very bad looking BASIC)
