R.O.B. emulation

Anyone ever had a try at R.O.B. emulation? I suppose you could have a try at simulating the robot (with this info http://www.google.com/patents/US4729563 ). But that is not what I'm aiming for: I mean actually low-level emulating the toy. For that, we'd have to decap the MCU to get the internal ROM ...

looks and plays very nice, I'm looking forward to the end result! =)
It has a bit of a Cave Story feel to it, intentional I guess?

Both of these boards seem to be the same aside from the PRG size limits. So let's say that I expand the PRG-ROM of a UNROM to 256K, would it automatically become UOROM?
the physical board: no
the iNES ROM for emulators: yes

the other question: yes

Aye, be careful there Dwedit, it could affect your reputation. Besides, mixing several pixel art styles doesn't work well (monsters from Crystalis, water from FF1, ..) :?

No offense intended, just being a nerd that is a fan of originality.

Since it's specifically about custom MSX2 Eggbert file formats and not about the NES side of things (assuming project Time Bird is for NES), I advise you to ask for help on the msx.org forum. Even tfh(fony) is a member there. :)

good luck!

That's... surprisingly awesome! :)
I won't say it's "the best", with quality stuff already around (eg. IMO the in-progress Chu Chu Rocket port, or Battle Kid), but it would definitely be in my top list.

Even though nestest passes, the SMB problem still sounds like a CPU bug to me. Try blargg's CPU test too.

How about an audio recording of nesdev_anthem.zip B00daW? :) yay, the same concept on TMS9918 family graphics chip, as you can see, amplitude can be changed by changing brightness. http://www.youtube.com/watch?v=rGA_fVegAb4 I spent most of the time creating note- and lengthtables. :( sourcecode here...

blargg's example is the same as you describe Dwedit, it's just (much) clearer if you switch the cables.

On another note, it shouldn't be too hard to add this PPU noise as simulation to emulators, provided that the emulator supports borders, not just the 256 pixels per line.

Thanks, this is a pretty smart optimization for when noise is not in use. :)
In the thousands: I don't think that's needed.

not-completely-off-topic: any candidates for n = ((n << 13) ^ (n << 16)) & 0x10000 | (n >> 1) ? (AY8910 noise LFSR)
Which program did you use?
