Re: New size coding contest "ZX Spectrum effect"

On latest Revision 2024 Demo Party, i saw what people can do in 256 bytes (not kB or MB). This is not possible for regular people.

I'll try to post links to Youtube later.

Re: New size coding contest "ZX Spectrum effect"

Hello :)

In Your code is little error.
In loops you must started from x=1 and y=1. Because you did [x-1][y-1].
And first index = x - 1 = -1. The same for y.

Okay, we have the first player, who next?

Rules:
- must run on ROMv5+
- 32KB+ machines
- no SYS functions
- all tricks allowed

The winner is: shortest gt1 file.
