Re: Curious about MMC5 5209/520A registers

Oh that Vertical split thing wiith $5200-5202, right ?? I was going to try that out once for the Pause Menu, but i was really disappointed that it wasnt allowed for EX Attributes. :( Apparently only works with regular nametable's stuff. I would of split the menu screen in half. scroll one side up, o...

Re: Curious about MMC5 5209/520A registers

Ah okay. Too bad about the 5800-5BFF area then. :( going unused pretty much. Yea well, i'll never be using Scroll F0-FF anywhere anyways. I use Y position E8 on a few of the menu screens like Time Attack, Achivements, and Save-Load Game screens. Never F0+ though cause it creates a empty black line a...

Re: Curious about MMC5 5209/520A registers

Hmm that's pretty interesting what you guys are saying. Yea i was going to say, dont forget 4 MI, which is the base megaman 4 ... with CHR-RAM, and mmc5 mapper too. I have a couple other questions then too if I may. -- I'm assuming the 5800-5BFF stuff is not supported in any emulators too ?? even th...

Re: Curious about MMC5 5209/520A registers

Oh i see, no emu's. Okay then, oh well. So then just to clarify... a 0001 would of made an IRQ literally the instant you write it to the registers just because it's 1 CPU cycle ?? (like right after the STA 5209, and before the next opcode literally) ? Should mention that on the wiki ...cause i dont ...

Curious about MMC5 5209/520A registers

Hey there. I was just curious about this "hardware timer" thing with 5209/520A registers for IRQ's. On here: http://wiki.nesdev.com/w/index.php/MMC5#16-bit_Hardware_Timer_with_IRQ_.28MMC5A:_.245209_read.2Fwrite.2C_.24520A_write.29 Is there any real general purpose use where one could use this for so...

Re: What code editor do you use?

I always watched whenever puresabe would stream programming live on twitch, for his SNES megaman 7 hack, and he always used a program called "sakura editor". And that tempted me to want to use what he uses. So ...me - Sakura Editor with English plugin. And a macro's file from puresabe's Rockman 4 Mi...

Re: Why was the GBA sound so poor?

this prob will sound silly, sorry. :( I always personally hated how the Sonic Advance games sounded. I always thought it felt like it was making just nonstop farting noises/sound. Especially the first sonic game (sonic advance 1) .. i dont know how to say it really but one of the sound channels is e...

Re: looking for a coder[paid]

Re: looking for a coder[paid]

alright.. i sort of have a rough idea of what's going on with the wrong warp thing. After comparing savestates in the 1st room of the dungeon and leaving. 1 that's normal, and your savestate that has the wrong warp. I found out that the uhhh "return address" or "exit" or whatever you wanna call it, ...

Re: looking for a coder[paid]

okay got your savestate and saw the wrong teleport to other place then. Yea. unless the game actually crashes with that, then there's no way im ever going to be able to figure that out, cause i know absolutely nothing about this game, never heard of it before you started your thread the other day. I...

Re: looking for a coder[paid]

Oops, i missed 1 of the music engine JSR's. (delete my custom JSR cause it was "during" NMI) Sorry about that. May still be more spots. It's impossible to know truly 100% for sure cause we dont have source code of this game. So i can only do these edits in the hex editor. https://www.mediafire.com/f...

Re: looking for a coder[paid]

It's the same situation again. :( The game was in the middle of a bankswap, it did a lda #$06, STA 8000 ..which means it's getting ready to change the 8000-9FFF NES memory ya know ?? NMI now triggers nmi is finished and when it returns, it goes with the 8001 ...
