Re: Coredump tool

coredump-v1.7-screenshot.jpg Today I present version 7 of this tool. (versions 5 and 6 are part of action53) Every byte of this code has been chipped down and optimized so that it all now fits in less then 2 pages at 496 bytes total, including the compressed font. If located at $fe00 there's even e...

Re: Donut NES CHR compression

Yep, that's what happens when I write code without actually running it. Thank you. It's been difficult keeping a stable programming environment when moving over to a new computer for the 5th time this year. Alternatively at this time that dup block function could just be removed entirely (by changin...

Re: Donut NES CHR compression

I wanted to push this beta out to get a pulse on if I'm doing this right, lot's of stuff needed to be done including more info on different ways to use the 6502 decoder, a demo, and a web accessible Readme. When finished I'll update the first post and remove this temporary attachment. Edit: removed ...

Re: Donut NES CHR compression

So I can still see what's going on in the discord server but I'm unable to participate there so if somebody can forward this message there I would appreciate it. Hey, show of hands (via emoji reaction) if you are interested about Donut CHR Compression, so that I can know where to focus my efforts. I...

Re: Troubles with making a twitter account

Ok the saga continues, First those appeals get eaten if you are still on a "sus internet connection" (I know because I tried several times in different locations and the only one that got through was not at any of my usual internet spots). But even after the reactivation I still don't thin...

Re: Troubles with making a twitter account

This all occurred 22:20 UTC and I was emailed the notice. I tried re-installing the app and logging in just now and the account is still banned. I'll agree it was due to a buggy automation, but the effects of the bug is permanent for me.

Re: Donut NES CHR compression

So to answer why that bug, it wasn't due to any design requirement, but was merely a case of me being dumb wanting to save a "cpx #64". I removed that footgun in the wiki copy, but beyond that I wanted to chat a bit in the presence of people who were interested, but that impulse has been s...

Re: Troubles with making a Discord account

I've necro-bump this thread as at least it's related social media account set-up. OK so today I realized there was quite a few people at the Discord server that I needed to talk to and confusions and troubles that needed to be addressed due to my absence, but what occurred today has got me so irate ...

Re: Donut NES CHR compression

So occasionally I check in the Nesdev Discord (with disposable sessions due to ... reasons) and there's concern about the copyright / IP licensing of all this. My intent has always been that the block format, and the ability to encode and decode the format, aught to be public domain and unencumbered...

Re: Using DOSBox with Linux Mint?

As far as I'm aware the x816 versions for what I worked on to convert to ASM6 should be the second oldest git commit of x816-things there.

Re: How does background collision work?

Is it possible to trick the nameable to reveal where certain tiles I consider solid are? I doubt you would want to generate a list of all X,Y coordinates of tiles whose value is Z (there's only about 29000 CPU cycles per frame after all). Rather you would want to figure what range of tiles to read ...

Re: Lossy compression for NES screens

It was pointed out that the 2020-12-07 version of this was causing segmentation faults with large (about 49000 tiles) images. The patch for this is to change the variable types and change the if statement for jrrtilevq_distance_matrix_coords as follows: static uint32_t jrrtilevq_distance_matrix_coor...
