Can a RBG Mod'd NES output RGB and COMP at the same time

I've tried searching but haven't found an answer yet...

Does the mod let you output both RGB and composite at the same time.

The RGB would be going to the TV and the composite/s-video would be going to a video capture device.

Re: Score, etc

Perfect - that makes it a lot easier to read. Thanks for the clarification...I'll try to implement this. It's simple enough to navigate and should work just fine for my purpose. Here is a full example. Sorry about the formatting. EXAMPLE A= #$80 = 128 DECIMAL hex_to_bcd_8_bit ; STA $45 ; $45=#$80 L...

Re: Score, etc

Yes, I posted this fast so yes the JSR's should have been divide_8_bit. I edited my post. In this game $3E-$45 are used as local variables for routines. The 'A" register holds the hex number that is to be converted. The result of the conversion gets saved in $44,$45 where 44 is the low digit and $45...

Re: Score, etc

This is how its done in TSB. But probably not the most efficient way possible. All of these variables are temporary variables. INPUT: A= hex number to convert RESULT: $45= high digits $44= low digits hex_to_bcd_8_bit ; CONVERT HEX NUMBER TO BCD(A= HEX) STA $45 LDA #$0A ; SETS TO BASE 10 STA $44 JSR ...

This. It's cool as an art/collectors piece but I can't imagine actually wanting to play games on it.

Re: Value constants in NESASM3

If the assembler is case sensitive then then a style convention would always make it obvious but bit more tedious to type I guess. You could use post-fixes like so to make it obvious. CONSTANT_C = #$01 MYVAR_Z = $01 MYVAR_M =$0400 or CONSTANT = #$01 zeropage_z = $01 memory_m = $0400 But I guess this...

Re: Which assembler should I be using?

If someone REALLY wants an IDE this one isn't bad. Sometimes I like it for doing small little hacks It's definitely not as powerful as ca65 or nes asm6 but might be good for a beginner. It doesn't support multiple banks. It has some basic directives such as .rs, .macro, .org, .if, .db, .include, htt...

Re: Help with a bug..

I'm assuming bullet_speed is variable stored in memory that is used the routine and not a constant since its not in all CAPS Perhaps something else is modifying the bullet speed variable before it gets used in the routine? But the loop itself looks fine to me otherwise. Unless you meant to check the...

Re: Demptronic NFL Football

Many of the things in TSB that are outdated or broken can or have been fixed but good luck to you.

Building a football game from scratch with just one person will be a major project.

Re: My experiences with InfiniteNESLives and Krikzz

There are several sellers (websites) now. You have a lot more options. But when it comes down to it, you're still taking a risk getting something like this. I am not saying people getting ripped off or "given the run-around" is acceptable -- far from it -- but I am saying that you have to be aware ...

Re: Embedding a ROM in an emulator

I played around with something like what you are talking about in the halfNES emulator since I could follow the source code enough to modify the emulator. I didn't really embed it but you could. What I did was have it auto-load an encrypted rom from a web location. The web location was also encrpyte...

Re: 6502 cooperative multitasking framework

Tecmo super bowl uses a round robin thread/task based system as well. There can be up to 7 tasks that it cycles through.

It has functions for creating, resuming, sleeping, and ending tasks.

Re: Hi-Def NES HDMI Adapter for the NES

With the amount of work that went into this(development,testing, assembling,etc) they definitely deserve to get whatever the buying public is willing to pay.

Amazing job kevtris!
