Well, there's the JSW48 game engine, the JSW128 game engine, and there's
engines that can cope with 6-bit, 7-bit and 8-bit rooms, and there's
engines that hold the rooms in 256 and 1024 bytes of data. To cover all
varients you'd need to specify all three!

How about xx, giving:
JSW48x64x256 - The standard JSW
JSW48x128x256 - The JGH 7-bit room patch
JSW128x256x256 - John Elliot's JSW for the '128 with 8-bit rooms
JSW128x64x1024 - John's new JSW64/JSW128x4
MM48x20x1024 - The standard Manic Miner

or xx, giving:
JSW48x6x8 - The standard JSW
JSW48x7x8 - The JGH 7-bit room patch
JSW128x8x8 - John Elliot's JSW for the '128 with 8-bit rooms
JSW128x6x10 - John's new JSW64/JSW128x4
MM48x5x10 - The standard Manic Miner

You can recognise a 7-bit room engine by the instruction at &8915 being
XOR &C0 instead of OR &C0.
