Just guessing, I've no experience with this.
1) Use the converter tool to dump the exported function names from the original .obj
2) look for an exported name which looks like RNBOsproFormatPacket
3) use the name conversion option of the converter tool to map the name you found to SPROMEPS_RNBOSPROFORMATPACKET$RB_SPRO_APIPACKET_PTR$WORD$$WORD (see manual)
4) do this for all 13 functions
