Such documentation is known to entice certain members of the Yahoo Group more than the games themselves might!!

Regarding the 'Jet Set Mini' readme, whilst I attempted to give a thorough apportioning of acknowledgements for active and passive contributions, one thing which I omitted to include is a specific credit for the notion of a 'Room Setup Patch Vector', as distinct from a 'Main Loop Patch Vector'.


'Jet Set Mini' makes heavy use of both tools, so I would like to put on record here my thanks, as far as I understand the situation to be:


- to John Elliott for devising the 'Room Setup Patch Vector', and presenting it as a useful feature of the JSW64 game engine (though I inserted the tool into the 48K 'Jet Set Mini' independently, I followed the same principles);


- and to Andrew Broad for bringing the various types of Patch Vector to my attention, and giving some helpful examples which enabled me to get my head around the distinction.


N.B. In the 'Jet Set Mini' readme, I have acknowledged (or at least alluded to) the fact that Geoff Eddy introduced the general concept of the Patch Vector (by which he was referring to what later became known as the Main Loop Patch Vector).

Incidentally, in the 'Random+ Mode' of the separate project 'Jet Set Mixup', I have come up with a brand new tool, which I have dubbed the 'Item-Collection Patch Vector':

A subroutine is CALLed from the 'Draw the items' routine (#93D1-#9455) whenever Willy collects an item, and this causes a special effect whose exact nature is dependent upon which item was collected (i.e. where the item's definition sits within the table at #A4xx-#A5xx).
