Re: New Game for the Game Boy: INTO THE BLUE

I think it should be fixed so that the scores are not always a multiple of ten, by dividing the existing scores by ten, so that more points will fit on the display at once, because currently it is not enough.

Re: Is NES/Famicom detection possible?

Yes, duty swap is something that's known to be inconsistent across clones, and I don't think it's possible to test for without human interaction. Actually maybe you can test it if you really wanted to; if it is a Famicom cartridge then the audio goes through the cartridge, so it may be possible to ...

Re: Initial (semi) release of nesromtool2

The bitff and ffbit programs of Farbfeld Utilities require you to specify the colours. ahhh, ok. I got it. that makes sense. thanks for the clarification. I wonder if that would make sense for my tooling. My thought is that the user should be able to control the format of the file from their graphi...

Re: thread discipline vs thread dynamism

My opinion is NNTP is better. (You can also add additional MIME headers for special purposes if you need to do so, such as denoting questions and so on whatever.) Hopefully, you can then make a SQLite virtual table that can be used to search (although the SQLite virtual table mechanism does have som...

Re: Initial (semi) release of nesromtool2

I wrote Farbfeld Utilities, which can do these things. See the bitff and ffbit programs, as well as perhaps ff-strip, to deal with CHR files. See pngff and ffpng to deal with PNG files. Indexed colour is not necessary, though; these programs can work with any kind of PNG file. I'm curious how this ...

Re: Initial (semi) release of nesromtool2

These things may be good to have, but I have a comment about this part: There's also a pair of helper tools: chr2png and png2chr which can help during development so you can convert PNG files into CHR banks in your Makefile, for example. As long as the PNG remains in indexed color and only the first...

Re: Famicom NES repro clone

The Famicom/NES is in need of an open source and accurate clone. I agree, it is needed. Famicom expansion audio can be done by the cartridge; if there is a 60-pin cartridge connector then it can use such thing (you do not need to reimplement the expansion audio inside the console itself). For diffe...

Re: Is NES/Famicom detection possible?

The practical problem with user configurability is that users would find reconfiguring everything every time the system is turned on tedious. To atttempt to avoid that, you'd have to 1. make your mapper self-flashable, 2. exhaustively test that your configuration saving won't overwrite the game, an...

Re: Is NES/Famicom detection possible?

It is better to detect what input devices are connected instead That's fine provided that reliable detection code exists. I've tried to include detection code in my controller test program . But without a Famicom console, Famicom controllers, and a Famicom-compatible flash cart, I can't test detect...

Re: New Game for the Game Boy: INTO THE BLUE

This is cool! But I keep on having a problem with creating single columns of tiles and I can't clear them. Same thing I noticed (even though I try to avoid such a single column, by breaking the panels underneath and by other ways). But game still seems good though. Normally single colums start to p...

Re: Is NES/Famicom detection possible?

The only thing about AV Famicom is that the controller ports don't connect all of the pins, but this is probably unimportant. Except in something like Zap Ruder that's designed for two Zappers. In addition, Famicom plays mapper audio; NES doesn't without a mod, and I don't know what 72-pin famiclon...

Re: Is NES/Famicom detection possible?

I am not sure why you need to tell the difference between NES and AV Famicom, but telling the difference from NES and RF Famicom would be more useful, because RF Famicom has a microphone and does not have player 2 START and SELECT button. The only thing about AV Famicom is that the controller ports ...

Re: Famicom vs. AV Famicom Expansion Port Sound

I knew that the RF Famicom expansion port has only the internal audio (because I saw the schematics of it), but I did not know that it is different on the AV Famicom; thank you for mentioning it so that now we will know.

I believe you are correct. But you might be able to intercept RAM values if the game cartridge maps RAM into $8000-$FFFF (although most cartridges don't do that).
