Sinclair ZX80 / ZX81 / Z88 Forums

This is a game I wrote to demonstrate the capabilities of the z88dk standard monochrome graphics library.
Performances better than BASIC but not so enthusiastic, but don't blame the compiler kit.. the game relies onto portable functions, which may not be (yet) optimized for speed but this permits a lot of flexibility: it can be run on a wide variety of targets, graphics size can be determined at compile time, and so on.

Game keys are Q,A,O,P

I'm attaching it diferent flavours, let's begin with WRX 16K RAM, sorting them by speed it will be:

microman-full-big-wrx.p
microman-full-small-wrx.p
microman-compact-wrx.p
microman-compact-fast-wrx.p

If you are a good videogame player you won't like this port very much, you'll probably prefer "One Little Ghost"

The Andy Rea graphics trick is slower and the big sprite versions were far too boring, but here's a couple of compilation attempts with small sprites.

The Memotech WRX mode has been tested on the real hardware (see here: http://www.z88dk.org/wiki/doku.php?id=l ... _functions), but it is a bit glitchy.. and I never found the reason for it.
EightyOne looks even slower in MTHRG mode than it ARX mode, it could be due to my libs, though.

Well, here's an almost playable version, even if still a bit slow.

Thanks for all the love you're giving our little machine!

For some reason I could not get this to work on ZXSpin.....

There must be a setting I am missing - using the memotech hi-res helps but you just get a 1/3 screen.

For the ARX mode I use EightyOne by disabling WRX and enabling the "RAM" page in low positions (i.e. over the ROM).

One of the original reference pages is here:

Excellent - that works fine

I am mighty surprised that NTL page still works, haven't had that account for about 8 months when i moved house.

Hope you're proud of what I've done with your ARX trick
Are you keeping your articles somewhere ? We're risking to loose them, I remember another (more detailed) page about this video mode but I couldn't spot it anymore.

Hmmm, looks **so** cute! I love it.

Will test it when my Amiga album is finished (I must have some place on my desk!! And A500 with 2 additional cards - Motorola 020 20Mhz + 132Mb of RAM - takes SOME place! ).
