Event id #2678 : The 128b font compo

Welcome to the 128b font compo!

The goal is to create the most legible, stylish, and/or awesome font using an executable program no larger than 128 bytes. The assumption is that the ROM font will be used as a basis somehow, although this is not a formal requirement.

The deadline is end of April 8, 2018, in a time zone of your choice.

The compo is held at CSDb, and the result is determined by the weighted average rating (including non-public votes). The ratings will be sampled one week after the deadline, end of April 15, in a time zone of my choice.

Judges are asked to consider screen codes 00-3f only. This comprises the uppercase letters, digits, and punctuation. The rules do not mandate that reverse-video characters work, so it is all right if the cursor doesn't work properly.

I reserve the right to modify the rules if there is a good reason.

Technical requirements

Maximum file size including load address is 128 bytes.

The program must load to the default location ($801), and must be executable with RUN. The new font should be installed at address $3800, after which the program should return to the BASIC prompt, with the VIC bank register ($d018) updated to point to the new font.

The entry should be uploaded in .prg format.

A person may be creatively involved in at most two (2) compo entries. (Idea/test/help credits don't count towards the limit.) It's alright to withdraw an earlier entry in order to submit a new one, up to the deadline.

Template

The following template code is offered as a convenience, and may be used as a starting point. It simply copies the default ROM font.

  
        .word   $801

        *=$801
        
        .word   $80b,1
        .byt    $9e,"2061",0,0,0

        sei
        lda     #$33
        sta     1
        
        ldx     #0
        ldy     #2
loop
src     
        lda     $d000,x

        ; ...
dest    
        sta     $3800,x
        inx
        bne     loop

        inc     src+2
        inc     dest+2
        dey
        bne     loop

        lda     #$37
        sta     1
        
        lda     #$1e
        sta     $d018

        cli
        rts


Happy hacking!

"Judges are asked to consider screen codes 00-3f only. This comprises the uppercase letters, digits, and punctuation."

How about the non-letter, digit, punctuation bits of that code space, such as @, arrows, #, £[] (which cannot be relied on to behave the same way with all character roms), etc.?

Good point. Let's say that @, #, £, [, ], and the up and left arrows should be ignored by judges.

Also let me add that the letters in the font can be uppercase, lowercase, or any combination.

Yeah, why not! Multicolour is hereby allowed in the compo (such entries must set d016 properly). It may not be in the spirit of the original vision, but if somebody can pull it off in 128 bytes and get a charset that is good enough to earn decent ratings, then that would be awesome.

Trying to do a 2x1 font. Will it be disqualified if it displays all the chars, but doesn't return to the basic prompt?

I've located new charset at $2000-$2fff. Does it disqualify me? :(
