Re: Toledo chess program

Thx. On PC with i5 3GHz, the answer is instantly. On Gigatron emulation, I had to wait probably "hours" (broken up - hat to go).
I will test on real hardware the next days.

Re: Toledo chess program

Thanks! I just did the required changes for modern C++ compiler. But now I replaced all occurrences of 1e5 with 2e4, and 1e9 with 3e4 and it runs fine now. Now we just need to figure out, how to have computer play black ;-)

Re: New size coding contest "ZX Spectrum effect"

Maybe someone will suggest another? I am thinking of: "Write the nicest/most interesting/awesome demo/intro/graphic effect/game whatsoever" Any language, any size (but smaller is beautiful), could run in 32k/64k/128k, can be run from sd card or rom ;-) Should be run in romv5a, but if requ...

Re: New size coding contest "ZX Spectrum effect"

Here is mine solution (not sure, if screen is correct this way?): int main(void) { int x,y; for (x=0;x<160;x+=2) { for (y=0;y<120;y+=2) { screenMemory[y-1][x-1] = 0; screenMemory[y][x] = 0xff; } } } -rw-rw-r--@ 1 ich staff 141 13 Mär 17:53 Makefile -rw-r--r--@ 1 ich staff 265 13 Mär 18:09 zxs.c -rw-...

Size / other effect coding contest I_nter S_tellar M_atrix

Sorry, I could not resist. I experimented a bit with new contest suggestion by PhiBrizzo. The outcome looks interesting (in my opinion) and remains me a bit on the scene in the movie Interstallar, where actor is in the 5d "room" ;-) I was also impressed by the size of just 140 bytes gt1 fi...
