Awesome - thanks!

Thanks!  Hope it works out successfully.

It's cool to see development on the firmware moving at a fast pace again!  The Retrode already covers the vast majority of my collection, but there are a couple of cartridges out there that I'm interested in; one of those is Super Street Fighter II for the Genesis.

From the documentation (, it looks pretty straightforward:
  • read 0x000000 through 0x3FFFFF into a 5MB buffer
  • write 8 to 0xA130FD
  • write 9 to 0xA130FF
  • read 0x300000 through 0x3FFFFF again into the last 1MB of the 5MB buffer

But, I don't know anything about microcontrollers, so I don't understand the complexity involved in actually implementing that.

Is SSFII worth a look for a future version of the firmware, or is this tougher than it looks?  Thanks!

Edit: I'd be happy to chip in a US cart as a donor for testing.

There is also the issue of byte-order with N64 ROMs.
From what I understand, people have been arguing for a long time over what the correct byte order is in N64 ROMs.

(like if you open an N64 ROM in a hex editor, there should be at least a game title in ASCII. IIRC, No-Intro uses the byte-order that creates a jumbled title (like instead of SUPER MARIO 64, USEP RAMIR O46, or whatever)
Yep, this was it.  Thanks!

I'll get (or write) a tool to swap endianness (dd conv=swab won't work, as it swaps byte pairs; it looks like N64 conversion involves pivoting quads) and try again.

Another vote for the Linux live USB firmware method.  It's far more reliable than the Windows method in my experience.

I'm using a Retrode running v0.19, HW ver 2.2, plugged directly into a USB 3.0 port, the N64 plugin from DragonBox, clean cartridges, and the voltage is set to 3.3V.  I'm running Win10, and am using PowerShell's Get-FileHash cmdlet as my verifier.

However, none of my hashes match No-Intro.  A few examples (these are my hashes, not No-Intro's):

Doom 64: B67748B64A2CC7EFD2F3AD4504561E0E
F-Zero X: 753437D0D8ADA1D12F3F9CF0F0A5171F

GoldenEye: 70C525880240C1E838B8B1BE35666C3B

(And many more; I tried to pick common cartridges that didn't have multiple variants.)

These load in RetroArch Mupen okay, so I'm not sure if I should be worried that parts of the file are corrupt.  Is it normal to get dumps that don't match?
