The following links displays the modes with all kinds of information (even with screenshots). http://gury.atari8.info/card_graphics_modes.php

@carisson you're right, the VIC-20 is a fine machine for it's money but it's in a different league than the 800. And some ports of games are really great (or maybe the best) on the VIC-20. Gridrunner 1 & 2 (Matrix) from Jeff Minter for example. @2600 perhaps an advice, download a couple of (good) emulators and try it yourself. Both are fine machines, but different in capabilities and prices. What suits you the best is a personal thing.

Nothing against the VIC 20, but it's an upgraded PET in a small case. The 800 is better. And about Beebem, I'm using the linux version without any troubles.

You're welcome and it isn't easy to change a BASIC keyword, after all it's all in ROM. It's a British computer, so we have to deal with ColoUr

L. 10 MODE 2 20 REM SPRITE (VDU 23,REDEFCHARACTER,8 VALUES) 30 VDU 23,224,24,60,126,219,126,36,66,129 40 REM BLINKING COLOUR FOREGROUND 50 COLOUR 11 60 REM BACKGROUND COLOUR 70 COLOUR 128 80 CLS 90 REM PRINT THE SPRITES (224) BESIDES THE TEXT 100 PRINT CHR$(224); " Bomb disposal "; CHR$(224) 110 REM SET FOREGROUNDCOLOUR BACK TO WHITE 120 COLOUR 7 130 PRINT:PRINT 140 INPUT "Which number"; X 150 IF X=10 THEN 160 ELSE GOTO 180 160 PRINT:PRINT"Phew" 170 GOTO 190 180 PRINT:PRINT"Retry" 190 END > In line 30 is the sprite, with VDU 23 you can redefine characters (in this case 224). the values after that are from an 8 x 8 grid. From left to right the values are : 128,64,32,16,8,4,2,1 000XX000 = 24 00XXXX00 = 60 0XXXXXX0 = 126 XX0XX0XX = 219 0XXXXXX0 = 126 00X00X00 = 36 0X0000X0 = 66 X000000X= 129 It isn't that difficult I believe. The colours are random picks and there are lists which colours are possible in the different modes. Good luck!

No problem, Your example is not in BBC basic so I rewrite it a bit to make it work

A few days ago I compiled the Beebem emulator for this machine (Ubuntu) and I have an Acorn Electron for almost 33 years so I know a bit about BBC basic Due the fact that BBC basic has already has a built in assembler I guess PEEK and POKE instructions were unnecessary If you don't mind I can put some example sprite etc in your listing, just to make an example?

I don't know if you're using a taperecorder in that case it would be with: SAVE"name" Commands must be in capitals. Most graphical stuff can be done with the VDU command, VDU 23 is (I assume) for making sprites. Peek and poke as commands don't excist in BBC BASIC, more or less can be don with the question mark.
