I can't seem to find out how to have blocks of code that share the same memory area... To be able to switch banks of code, you will need to grasp what the cartridge you will be coding for is capable of and what limits your compiler has. Taking in my example(...alone as it seems), using Telemark Ass...

...and done. Tetris: OXKOKESU ZOKOSATI XVKOVEOO Nintendo World Championships: OXXOASSU ZOXOPSPL XVXOZIVO This forces every piece (besides the first :?) to a straight piece. They are also rotatable. Believe me, I tried to find a space with a crapload of $12's to make a one-line code, but alas I was u...

Anyone ever go to the minus world in the NWC cart? Just did. Same old -1 we know and love. Also, a while ago I ran through the FDS minus word and recorded it: http://www.youtube.com/watch?v=xB2i-QOsBpw A great code would be make tetris always feed you lines! Good idea, I'm workin on that right now...

Got my security bits in today, and decided to clean all my aging cartridges (that I haven't cracked/canibalized yet), and noticed that I posess 3 revisions of MMC3. Now what I'm asking is are the differences from B to C. I've noticed (in prior experiments documented here on these forums) that the sc...

Talk about minimalist changing. Okay, I modified some loopyNES code I had lying around to not IRQ on the counter (which, after looking at a board, can be deemed innacurate anyways...I was going by scanlines (y'know, the chr address line trick), which is how MMC3 and MMC5(I think) do it...) Played th...

Then how does it know to switch to the next game? And where does it store the score? They had to have hacked the games even if only to add auto-starting and auto-finishing. Nintendo has source code to their games, obviously. The cart uses WRAM...and I checked in and it seems that there is quite a b...

flagrant copyright infringement Uh. Duh...even if one were to repro the cartridge with a 20-whatever binary counter and and aditional 161 to control the hi-bit banking, you still would have to copy the cartridge data from a rom image in the first place. Getting caught doing that alone (without perm...

Can you do a forced write (setting the software to a specific chip) without verify? Do that without a chip in the programmer the first time around, and you'll probably be good. I'd say it's a small software glitch, but it could be hardware. I remember Pentium(1)-based packard bells had to have the i...

There's a good chance these both use the same engine...just a hunch....

What about Dodgeball? I remember that game being annoyingly slow.. I'll add that to my most wanted list. That game feels like it's programmed to run at a lower rate though, but it's nothing that can't be tested. [man, who disables embed code...]...anyways: http://www.youtube.com/watch?v=fgkKftUQy-8

the instructions are available elsewhere, but I brought up the discussion of Kirby's Adventure causing slowdown, with a fix of using an overclocked CPU to eliminate it. http://img413.imageshack.us/img413/90/profilecl6.th.jpg The image pretty much shows everything I did. Although pulling up the ppu's...

Match the PCB thickness. Thicker is trouble, think of a game genie stuck in overnight. That usually warps all the pins.

Overclocking an NES...I'll have to try this just to see how well it'll work...although I'm having enough problems with my 1-wire cic-less front-loader.

+Kirby's Adventure Never got to try an actual cartridge. But it looks like their IRQ timings are in order...then again, that will really shine with Mario3's "inconsistencies." Is it just me, or does the game really slow down in some parts;The music still gets all the cpu time it needs, but...

Someone with the tools to check:

The $5010 address doesn't return open bus, and some carts aparently have been known to use the lsb.
