Mailing list

A mailing list has been set up to discuss GoMMC (and GoSDC) related topics. This is definitely 'the place to be' if you want to follow developments and ask questions.

Join the mailing list by subscribing to Yahoo Groups (for free) here, and then subscribing to the 'GoMMC' mailing list here.

Third party tools

GoMMCExplorer allows you to (among other things) view, add to, remove from, backup and restore your flash card contents. It supports both GoMMC and GoSDC.

DFS Explorer or ADFS Explorer can, respectively, build DFS or ADFS disc images from files. Use OmniFlop to turn them into BBC-readable floppies.

OmniFlop can build BBC-readable floppies from DFS or ADFS disc images. Use (A)DFS Explorer to build your disc images.

Disks and tapes for GoMMC

Always wanted to have a large disk and/or tape collection for your GoMMC, e.g. the Stairway to Hell collection ? Software is available to help.

Download the software here, and follow the instructions in 'readme!.txt'.

Playing video with GoMMC

GoMMC's transfer speed is high. In fact, it's as high as it will go on a BBC, which is roughly 220 KB/sec. For a bit of casual entertainment, I've hacked together a video player that harnesses this raw transfer power, and a few videos to run through it.

Download the player here, and follow the instructions in 'ReadMe.txt'. The available videos are : 'bugs bunny' (7 MB, mode 4), 'flip out' (4 MB, mode 4), 'flip out' (4 MB, mode 5) and 'bugs bunny' (139 MB, mode 4).

GoMMCio source code

The source of GoMMCio.exe is available, to enable porting to other platforms than Wintel PCs (although Linux and Mac OS are already covered).

Download the latest version here.

Patch for Master Elite

The Master enhanced version of Elite wants to use sideways RAM bank #6. If GoMMC occupies that bank, you're out of luck unless you patch Elite to use bank #4 instead.

Recipe : Download the disc image here and unpack 'Elite.img'. Download my patch program here and unpack 'patch.exe'. Then run patch.exe in the same directory as 'Elite.img'.

Alternatively, if you so desire, change the following bytes in 'Elite.img' by hand (e.g. with a hex editor) : at offsets 0x192AD, 0x192B6, 0x192E5, 0x1932F, 0x19338, 0x1D971, what was 0x06, 0x06, 0x36, 0x06, 0x06, 0x06, becomes 0x04, 0x04, 0x34, 0x04, 0x04, 0x04, respectively.
