As long as the glitches caused by corruption are easy to reproduce, I might try a quick test or three. Awesome, just tell me which ones you want and I'll send you the IPS patches for them. JMP would probably need three codes: one for the opcode and one for the address. Not exactly. You could just h...

The nesdev.com board community is TINY. You might get more response from a busier board. (yes, I've watched these...) Yeah I'll think about doing that. I've been dealing with personal issues that have caused some depression, so I've been really lazy spreading word about my vids. I watched them too....

Aw come on.... no one? this was a really good one too, and I would think you guys out of everyone would appreciate these more. ;/

In honor of Super Mario Bros. 25th anniversary, I decided to release vol 1 of Super Mario Bros. Watch it now!

I personally thought the one where he isn't wearing any pants was more amusing.

Probably. Funny thing is though my vids are more entertaining, haha.

Actually corrupting Action 52 would probably FIX most of the games.

Well, I made a new video! This time, I corrupt A Boy and His Blob!

You mean CORRUPT? Probably not, haha, but I happen to use my own tool for corrupting my roms.

These flashing horizontal lines look like palette writes. Palette writes might happen when VRAM loading code crosses over PPU $3F00-$3FFF. It looks like data lengths might have been corrupted. Interesting. I think it may also have to do with how the game draws the course topography at the top of th...

Alright guys, new vid is up. This one is for Bandai Golf: Challenge Pebble Beach . Now pay attention to the first 4 or so iterations. I seem to have run into a very similar.... effect.... the flashing screen with the horizontal lines and such.... what I want to know is, what exactly is going on ther...

When you change a 2 or 3-byte instruction to a 1-byte instruction, that single byte change can do a lot, since it misses the next few instructions, executing junk instead, until it can eventually get back on track. If it misses a jump, call, or return, that's an even bigger effect. Oh I know that (...

I used to do the same thing with random 6-letter Game Genie codes. I would keep track of interesting codes in a notebook and try variations when something would glitch up well. I have very fond memories of doing that as a kid as well. The Game Genie was my favorite NES accessory and the rom corrupt...

Sup guys. I know I haven't posted here a lot, but I felt that I should share my youtube series with you guys. Anyway, What I'm doing here is taking NES roms and running them through a Python script that randomly changes bytes in random locations (in PRG ROM). I then take footage from the now corrupt...

Most NTSC video signals are interlaced. Each frame all the scanlines on the screen are offset 1/2 scanline height from the previous. The NES video signal (and others from pre-CD consoles) trick most TVs into displaying the image non-interlace (progressive), so that every field's scanlines are in th...

I've noticed this on a lot of NTSC TVs. If you look closely, the scanlines on a TV don't stay in place. They look like they crawl slowly upwards. Is that the same for NES video output? how hard would it be to implement into the existant NTSC filter? Just wondering.
