You could try interleaving the bits from the two DPCM samples (That is the first 2 bits of the mixed sample is the first bit of the sample #1 followed by the first bit of sample #2). With this you'll also need to play the mix at double the speed to compensate for the extended length of the mix. It s...

I just wanted to bump to say that when I first saw this back in May it was the highlight of my whole day to an otherwise dull day at work.
Impressive juggling of OAM updates as well.

A much improved rewrite of this tool which is orders of magnitude faster, slightly better looking, and can handle tile flips, can be found at https://git.jroatch.xyz/jrrtilevq/

I should visit this forum more often.

Martin Korth's Magic Floor also seeds random levels from power-on RAM

Wow! That water animation sure gets my vote for one of the most awesome uses of CHR RAM, next to Brad Smith's NESert Golfing slopes.

TLDR; Don't worry about malicious code sneaking in a NES project. If it can, you may have bigger issues to deal with. To figure that out you'll have to define what "malicious code" is, and theorize how it might "sneak in". I'm amusing a we're talking about 6502 code compiled and assembled to run on ...

I'll just note the difference between the stats of DTE (from tepples and I) are due to different default parameters of the versions we have (use all available code-points vs using only the top 128).

For comparison, 2 other text compression formats specifically made for the NES in mind, Brad Smith's huffmunch , and Recursive DTE . |=========================================== |Algo | Compressed size | % |huffmunch | 15377 | 44 |Recursive DTE | 18787 | 53 |=========================================...

As casually documented, this has been broken since forever (or at least from 2013). I failed to report this issue when I found out about it back in 2014.

I also instantly recognized the font (and the entire order of the chr sheet.)

So as I was working on a potential Volume 5 an idea came up were Volume 4 could actually be the combination of compo 2017 and 2018. The upside of this would be that compo 2018 can make it to physical release sooner, the downside may or may not be that this Volume 4 would be delayed due to having to ...

Wow, I've let time slip by me at an unacceptable rate lately. I really have nothing much to show. My attempt at a compo entry failed to meet it's deadline, then I got distracted with programing traditional C programs. Last month I wanted to get back on track by compiling a focused list of games, so ...

My very first exposure to assembly was with single stepping instructions of a hello world program in the debugger of CodeWarrior on Mac OS 8 (Pre OSX). I decided that 68k was easier to read then PowerPC and went on to more exciting (to me at the time) things like viewing the resource fork of files. ...

I'm curious as to what ByteOff19 looks like that'd make UFTC solid do so well. Are there a lot of solid tiles or tiles with two or three solid quadrants? It's literally 80% solid black tiles. Sorry to disappoint. Both UFTC and XFTC top 128 do well on this one. Perhaps the reason I saw so few matche...

a heavily modified RLE codec (Donut). That's like saying PNG is a heavily modified DEFLATE codec. So I ran your scripts through some sets that I had.
