Re: looking for a coder[paid]

I agree with knight0fdragon. For changes like that, it might end up cheaper to rewrite the entire game. Shenzen Nanjing's NES games aren't known for their high quality really. Nesdev is more of a from-scratch board, romhacking.net would have more of the people who edit existing roms, but IIRC their ...

Re: cc65 now supports trampolines

Yes, though I see one obstacle: for some projects, .bankbyte would make more sense than .bank (no need to add stuff to the linker config if the high bits are already usable for that). So if you add that feature, please include such a toggle (in the file, similar to .smart, in addition to a command l...

In the 3d level, the way the character keeps pacing when standing still makes it look like they need to pee.

Re: Question about negative numbers

neslib has that, oam_meta_spr_clip filters out of screen sprites while still drawing visible ones.

Eh, Everdrive is far more useful. I think Memblers had something similar too.

Re: Could you broadcast to real Satellaview hardware?

But that's one-to-one, not one-to-many transmission :P I hear small sats are relatively cheap to launch nowadays.

It's not like folks blocking web fonts would have an emoji font installed though (I don't). Emoji are just as cancer as webfonts abused for icons.

Re: NTC: compression for short strings

Using the other end of the buffer as stack is smart. The straightforward iteration would've been ping-pong buffers. Though if the buffer-as-stack is small enough, a pathological input would cause corruption.

Re: NTC: compression for short strings

Looking at the .dte file's byte histogram, it's highly uneven, so it'd benefit even from single-byte Huffman. edit: Hm, if the DTE decoder was implemented by recursion, it'd blow the stack on NES. Worst-case recursion for this file would be about 162 deep, the entire NES stack can hold 128, and the ...

Re: NTC: compression for short strings

A quick calculation puts separate huffman trees at increasing the index by ~900 bytes, which may be too much in the precious common bank. OTOH it would also drop the total bitstream size by up to half in the best case. I also tried chaining DTE with this for kicks. It actually shrunk a tiny bit: $ d...

Re: NTC: compression for short strings

DTE seems to do rather well. I guess it doesn't get much weaker if used per-string? It looks like the source code uses canonical Huffman coding at some layer. Is there a document describing the format of the index? internal.h contains a description of the index. Not very detailed though. any string'...

NTC: compression for short strings

I invented a method for compressing short strings. Quite useful for text-heavy NES things, RPG dialog etc. https://github.com/clbr/NTC NTC - NES text compression ========================== This is a compression format intended for English text, as short strings. It uses second-order probability comb...
