Re: "wall" game for the Lamba 8300 / Power 3000
Well actually Lambda related z88dk files were patched to match the "old" Lambda ROM. It will be quite hard to make one binary that runs with the old and new ROM (as well as others). Currently the patched z88dk tree is still in a testing phase and "+lambda" now only compiles for the old ROM...

Re: "wall" game for the Lamba 8300 / Power 3000
So here is a little test program for the math functions... /* zcc +lambda -O3 -create-app math.c -lmlambda */ #include <stdio.h> #include <math.h> unsigned short frames @0x4034; int main() { int dframes; float M_PI2, M_PI4, M_PI6; char buf[3]; dframes = frames; M_PI2 = M_PI/2; M_PI4 = M_PI/4; M_PI6 ...

These extra characters look spectacular

Re: "wall" game for the Lamba 8300 / Power 3000
Yes indeed. Perhaps the Lambda version is slower because it always uses colour. There is a speed parameter for a delay in the C code, which I changed for the updated .p file above, but perhaps the delay could go negative, it is now constant. A universal program would have to poke the JP and CALL add...

Re: "wall" game for the Lamba 8300 / Power 3000
The game built for the newer ROM seems to be slow too (in the emulator), and slower than the one in the first post of this topic... But the zx81 version is ok. Fascinating

Re: "wall" game for the Lamba 8300 / Power 3000
You're correct, most addresses are different. The display routines are also a little bit different. Fortunately, the system variables appear to be the same. Here is a hopefully working version of the "wall" game:

Re: "wall" game for the Lamba 8300 / Power 3000
Hi Martin, does the attached program display something on your Lambda?
It was created by z88dk, by changing some things for the earlier ROM.
Stefano did amazing work when adding Lambda support!

Re: Let's calculate! - renewed arithmetic routines
Edit: (*): the ROM subroutine "03A8 NAME" can be used scan/evaluate such a complex string .... Yes, I left it in place at the beginning of LOAD and SAVE. However, the resulting string can only have A-Z. That is because the ZX81 character to ASCII conversion just adds $1B, otherwise it takes too muc...
