ZX81X2.ROM - and the big bang

[Moggy]

I think most of us are familiar with BASIC games creator Andre Baune and how he manages a fair turn of speed with his creations well I thought I'd try his Alien Mind a BASIC puzzle game, with the new fast ROM, and the speed increase is fantastic.

Try it and see.

Good stuff, I always liked this puzzler and have said many times I'd like to one day do a machine code remake... Well maybe I don't have to now

Speed on ZxMore (incl. Wilf's WHY-WAIT mod.): 263,5% @ 3,25 MHz , 529.3% @ 6,5 MHz

Andy: now its your turn using your 20 MHz Zeddy ....

Congratulations zsolt!

The YouTube has been removed for copyright reasons, unfortunately. I'd appreciate another.

When I get some time and a clear workbench I plan to take this baby out for a test drive. I'm thinking in terms of the Multi-ROM adapter discussed here: viewtopic.php?f=20&t=1006&hilit=Multi+ROM Haven't heard from the creator lately though. You still out there sascha2000?

Once again, way to go zsolt. An outstanding achievement.

Yesterday I used my old "Merker Zeddy" to test my own patches of the ZX81X2 rom:

http://forum.tlienhard.com/phpBB3/viewt ... rker#p1488

This Zeddy has a "language" card, which allows to map RAM to 0K-8K to test a new rom (a new "program language") in RAM, before an EPROM is burnt. There I tested my own rom patches: the original ZX81X2 rom worked well, but not my patched rom.
While I was looking on my PC screen to find the error in the source code of my patches, the screen got black and the light went out (main 16A fuse blown out).
I disconnected the Zeddy from mains and was able to switch on the fuse.

To locacte the problem, I connected the zeddy again to mains. Then I heard the BIG BANG in the Zeddy's power supply and the main fuse has been blown out again

Currently I am testing my rom patches on ZxMore (where I can load new rom images easily into flash rom)

I wondered why the lights went a bit dim earlier...
