This only happens sometimes. Have noticed on many different ROMs, so I don't think it is ROM specific.

i've already passed go test
, and when i load a nes:
./Fergulator ~/Downloads/super_mario.nes
-----------------
ROM:
PRG-ROM banks: 2
CHR-ROM banks: 1
Mirroring: Vertical
Mapper: 0x0 -> NROM
2013/04/17 01:23:14 No available video device
btw, my OS: Mac OS X 10.8.3, brew doctor
also passed.
First of all thanks for this brilliant emulator.
Some NES ROMs doesn't work with the Fergulator due to "Invalid opcode" error. I was downloading a lot of my favorite games from Internet and most of them work like a charm. Though some don't work while they are declared to be NES ROMs.
Micro Machines ROM doesn't work:
-----------------
ROM:
PRG-ROM banks: 16
CHR-ROM banks: 0
Mirroring: Vertical
Mapper: 0x2 -> UNROM

2013/01/11 14:34:41 Invalid opcode at 0xBFA8: 0x7

May be they are really for SNES, I don't know, please comment.

It doesn't look like RAM access is mirrored per this diagram:
http://en.wikibooks.org/wiki/NES_Programming/Memory_Map
I believe a simple fix would be to bitwise & the address with 0x7FFF
which should be equivalent to modulus 0x800.
func (m Memory) Read(a uint16) (Word, error) {
switch {
case a >= 0x2008 && a < 0x4000:
offset := a % 0x8
return ppu.RegRead(int(0x2000 + offset))
case a <= 0x2007 && a >= 0x2000:
return ppu.RegRead(int(a))
case a == 0x4016:
return Pads[0].Read(), nil
case a == 0x4017:
return Pads[1].Read(), nil
case a&0xF000 == 0x4000:
return apu.RegRead(int(a))
case a >= 0x8000 && a <= 0xFFFF:
return rom.Read(int(a)), nil
case a >= 0x5100 && a <= 0x6000:
if _, ok := rom.(*Mmc5); ok {
// MMC5 register handling
return rom.Read(int(a)), nil
}
}
return m[a & 0x7FFF], nil // <--- Mirroring handled here
}
Here's the command and the panic. When I run it, I can see a window popup on my screen for at most a few milliseconds. Then it disappears.
