I hope so.

Nice game.
Remind me of STRON.

That I can make. I will be waiting. Here is a test in BASIC: VAR X1, Y1, X2, Y2 TYPE BYTE VAR PLOTX,PLOTY,X,Y TYPE BYTE VAR INC,DX,DY TYPE BYTE VAR I TYPE BYTE LET X1=PEEK 16438 : REM COORDS LET Y1=PEEK 16439 : REM LAST PIXEL PLOTTED LET X2=PEEK 16514 LET Y2=PEEK 16515 LET PLOTX=X1 LET PLOTY=Y1 REM...

It's easy to write a LINE routine to invoke from BASIC.
Line from COORDS (16438) to PEEK 16514, PEEK 16515.
RAND USR 16516.
You can call the ROM routine at 0BB2 to PLOT each point.

Does this book includes a LINE routine?

Which book?

This app converts image to TAP:

On that site, there is another app who generates DATA statements but the image comes out splited into blocks 8x8.

But, if you want to generate a SCREEN then it is better bmp2scr or SevenUp, etc.

Can I get that fix now?
( For testing purposes, eh, eh... )

On the ZX BASIC compiler (Boriel) we can get the fix before the official release...

HELP! Please fix this bug on EightyOne 1.40: When I load this BAS file 10 LET X1=1 20 LET X12=12 30 PRINT X1 40 PRINT X12 and RUN the program then I got this error: Invalid expression in line 20. To solve this I must do EDIT ENTER on this line. But I have many lines like this and I dont want to do E...
