Blimey, been away for a while!

I had some free time this week to get back into the saddle and implemented a couple of simple versions of Conway's "Life". The first was in ZX Basic and took about half an hour to write, ages to execute. The second was in Z80 which took HOURS to write and executes in seconds...

Encyclopaedia Galactica

This game has been on my "to play" list for ages but I couldn't get hold of it (i.e. it used to be available to purchase online but the only link I had was broken).

Jonathan Cauldwell has released it this Christmas though and it is great.

The latest version of ZXDS even supports reading and writing of snapshot files (I am using .szx format) so I can play it on both my DSiXL and my PC. Bliss.

Raspberry Pi TNFS server up and running

Only just got it going so a little bare but you can mount "szeliga.zapto.org" from a Spectranet-enabled ZX Spectrum or you can use the Fuse emulator with the appropriate set-up.

Still having fun with SP1

Have now got an ISR that reads the keyboard, an animated sprite that will move up/down/left/right and diagonally and sound effects too.

Been playing with the SP1 sprite library today. Managed to get a sprite moving around the screen and bouncing off the edges

There's a good thread over at WoS where I've been getting some pointers from some kind chaps!

The screenshot shows a few of the masking methods available using the sprite library.

MetalBrain's SevenuP graphics package is good for defining the sprites and masks in a format that the sprite library can use.
