Re: Hardware test program for Genesis Justifier, Menacer and\or ALG GAMEGUN?

...And also cause level 2 interrupt for the CPU. The TH pin (7) on the controller port does that on high to low transition. The only thing that can create that transition is the comparator etc. in the gun and when its output isn't doing it the problem is either the comparator itself or its input isn...

Re: Does this song remind you of a song in an NES game?

Soundswise it is a lot like Duck Tales and some other Capcom games but the actual melodies etc. I couldn't recognize but I do experience some sort of familiarity moment too.

It helps there was no CIC equivalent in Famicom carts.

Re: FF4C and FF6C

Game Gear TV tuner drives the LCD directly, cartslot becomes passthrough directly to the LCD interface. I imagine similar thing is possible here too.

Re: Meaning of "SUPER HIK"?

That actually sounds plausible, I always wondered what it was as a kid too. Though I never saw any cart explicitly tell their size (though on the PCBs you often saw the Mbit sizes of the chips).

Re: Hardware test program for Genesis Justifier, Menacer and\or ALG GAMEGUN?

So what are you decerning the values of the 3 caps are that I didn't label? Your paint writing is kinda hard for me to read and I don't want to make assumptions. It looks like 10nf or is that 10uf on the 2 polarized ones? The polarized ones are 10µF 16V tantalums. The little grey one I left unmarke...

Re: Which Flash Memory to use for cart conversion

Alliance makes new 5V 2MByte sized parts but they are pretty expensive for the time being.

Re: bumping up file size

48KB is max size without mappers on SMS. For anything bigger the game will have to use one (perhaps the standard SMS mapper that most games use) but the game itself needs to be hacked to support that and that probably is not trivial by any means.

Re: Apparently the SMS is better than everything

I have actually found that "cough" giving a nice percussive quality to the noise rather than just a hiss like TI PSG which has a much "mellower" and "steadier" noise quality. 6.6667% duty cycle it produces when feedback is disabled is a problem for music since it isn't exactly some octaves different...

Re: Names used for tilemaps by original documentation?

It now dawned to me that it could be "table for the pattern generator" or "table of the pattern generator", data for the hardware that generates patterns (or at least that's how it could work in my language anyway). This makes it make sense for me, while the data way of thinking makes me think how a...
