Post subject:  Test VRC7 audio (incl. custom instrument)

I have written a program for the VRC7 audio: http://zzo38computer.org/nes_program/vrc7test.zip It includes source and binary for running in NES/Famicom emulator, or on a real VRC7 hardware if you have it. This program is public domain.

[I posted message in another section of the forum but you can remove that one; it doesn't work so well as this updated one]

Sorry for the five year bump, but a friend was asking about whether someone could make a VRC7 instrument tester, like the one CopyNES has but as a native ROM, so they could use it to try and refine the existing patch set.

I tried this ROM but I can't seem to get it to work. Every emulator I try seems to do something different, but none of them seem to have a working "cursor". Nintendulator has a black screen. FCEUX is unresponsive. Nestopia makes a high pitched whine and is otherwise unresponsive. puNES has the picture scrolled wrong unless you are holding a button...

What emulator did this originally work on?


This was the original version referred to, by the way: http://forums.nesdev.com/viewtopic.php?f=22&t=9093#p96785

I've found it to work with VirtuaNES 0.97. And also Nester 0.51b (with not-so-great sound quality).

Unfortunately I did not know so well how to write it at the time, so I did not to do a good job, sorry. It fails to clear the RAM and fails to do other important stuff too
