Default Emerald Hunt Lua help

As some of you might know, I am currently trying to create a Lua script which randomises the looks of the Emeralds you can find in a Hunt map. I have given the new sprites states like S_EMERALD1, S_EMERALD2 and so on (although those aren't the names I'm using in the final version of the Lua) and have a plan as to how to do it. The problem is that I only want to randomise the Hunt Emeralds which are chosen by the game, or to instead override how the game does it and randomise the spawn points in the Lua script (which in turn can mean using more or less Emeralds if the map maker wants to, but never more than the number of Emerald states - although if I did that, then I would need to alter the HUD to cater for up to 7 Emeralds) and give them a random sprite which would not be the same as any other Emerald in the Hunt map.

Can anyone help me out here with what I need to do? I've checked the source code and the Wiki, but so far I have come up empty.

Edit as of 09-09-2017 at 09:28AM BST:

I have decided to try and make them as a new Thing for the time being, and I have started work on the Lua script. The main problem now is that I've hit a stumbling block with regards to the spawning of them (and as a result, also regarding collecting them and completing the level if all of them have been collected)

Below is my current Lua code for the script in total:

Code:
-- This deals with the Ideya/Emerald Hunt levels

-- Make free slots for all Emeralds and/or Ideya (excluding the temp ones) plus use our own Hunt Emeralds
freeslot("SPR_IDEY","S_IDEYA00","S_IDEYA01","S_IDEYA02","S_IDEYA03","S_IDEYA04","S_IDEYA05",

states[S_IDEYA01] = {SPR_IDEY, A, -1,nil,0,0,S_IDEYA01} //Red Ideya or Green Emerald

states[S_IDEYA03] = {SPR_IDEY, C, -1,nil,0,0,S_IDEYA03} //Yellow Ideya or Blue Emerald

I've made some progress - in fact, I would say I just need to sort out the HUD, and then I'm done - but now I'm hitting an Access Violation when my code wasn't before.

Here's the code I've gotten so far - can someone tell me what's causing it, as I can't troubleshoot it?

Nevermind, turns out it's the SOC which was causing the errors.
