Press "M" this allows the block to move using the playing keys then press "M" again to give control back to the player.
You have to keep swapping between the two every time you want to move the block.

I have the two other games you mention and find them most enjoyable. What I would like to give a big thank you for is a program I found on type fantastic called SPRF - Single Precision Prime Factorisation. I could never get it to work at the time as the original listing was in my opinion a bit of a ...

Thanks for the info Paul, a most excellent site which is richer for your contributions and which I see has another of Mike Hyam's creations called Chart topper. This is one I play to death when I'm in the mood as simulations are my bag and confirm no errors with this one and is a nice piece of softw...

Line 5. After Gosport in the listing. There has to be 9 chrs in a line then a forward slash so 7 letters for Gosport, 2 spaces then the forward slash. to be honest though there is so much more wrong with this game as to make it totally unplayable. You will have to excuse my ignorance re Type fantast...

Ok Thomas check my late edit to the post above.

@Thomas. Hi Thomas just tried config "X" on both of my Xpand+ and all is ok. I don't think it's a ROM issue as in my experience the chip either works or it doesn't with no half measures. I have to speak to Charlie later tonight and will pass this on which I think will be the quickest solution. :D Re...

Excellent Shaun at last something else to add to my maths folder. :D I use the following, lifted from Rosetta Code, which may give you some further ideas. Analytic. 10 INPUT N 20 PRINT INT (0.5+(((SQR 5+1)/2)**N)/SQR 5) Iterative. 10 INPUT N 20 LET A=0 30 LET B=1 40 FOR I=2 TO N 50 LET C=B 60 LET B=...
