You can't upload game files (e.g. snapshot, tap, tzx) directly to the forum I'm afraid, the options are to link to something like google docs, sendspace or you could PM me and I can make it available on my own space :-)

Or if you have a finished game email it to us and we'll make it available in the archive in the next update.

Very short machine code from Weiv/Firestarter, 3 versions of a Snake game at 145, 137 and 95 Bytes! (the latest seems to be 95 rather than the advertised 93 bytes (?)).

Sinclair Joystick Keys 6789.

Can you do a better screenshot for its ZXDB entry? Then put your cock on the table and send us one :mrgreen:

No time to look at it in detail, but I can shave 1 byte by from the first two version by replacing

Code: Select all

	and $21
	cp $21
	jr z,begin
with

Code: Select all

	and $21
	jp pe,begin
Faster, too. (Not that it matters.)

Advertised 93 bytes length version of Snake: http://zx-pk.ru/threads/29039-snake-v-9 ... post959198 (At least I hope for it. I got the version from start post of the thread, and 95 bytes length was in the thread caption initially).
And even 84 bytes edition by krt17: http://zx-pk.ru/threads/29039-snake-v-9 ... post959494

Thanks for the info, we have missed the current ZXDB update (which will hopefully appear on this site tonight), but we can make these changes for the next update in about a week.

Nice screenshots but if you want to use them as part of ZXDB could you make them available as .scr please? (it is best if they are zipped).

That's quite a reduction :lol: , krt17 seems to know a thing or two about optimisation!
