If it's a load, it must be INPT0. If it's a store, it's COLUPF...
That said, it wouldn't be hard to fix the Distella output with a short
perl script:
---
#!/usr/bin/perl -w
%replacements = (
VSYNC => 'CXM0P',
VBLANK => 'CXM1P',
WSYNC => 'CXP0FB',
RSYNC => 'CXP1FB',
NUSIZ0 => 'CXP1FB',
NUSIZ1 => 'CXM0FB',
COLUP0 => 'CXBLPF',
COLUP1 => 'CXPPMM',
COLUPF => 'INPT0',
COLUBK => 'INPT1',
CTRLPF => 'INPT2',
REFP0 => 'INPT3',
REFP1 => 'INPT4',
PF0 => 'INPT5',
);
LINE: while(<>) {
for my $k (keys %replacements) {
if(/ld[axy]\W+$k/i) {
s/$k/$replacements{$k}/;
print;
next LINE;
}
}
print;
}

Save in a file fixdistella.pl, and run with:
perl fixdistella.pl disasm.asm > fixed.asm
It's not the prettiest code ever, and definitely not the fastest, but
it took under 10 minutes to write :)
