The correct sequence via JSGME would be as follows:
1. TriggerMaru_Overhaul_2-5 (with or without the optional modes)
2. Real Environment RSRDC_TMO by Kriller + Caustic
3. RSRDC_TMO_V502 (and patch)
4. 1.5_Optical Targeting Correction 031312 for RSRDCv502
4a 1.5_OTC_Realistic Scopes for 16 to 9 RSRDCv502
4b 1.5_OTC_Tokko's Revenge for RSRDCv502 (more aircraft and improved AI)
5. Ralles ModSoup for TMO_RSRDC_OTC V1.1
Pure graphic and / or sound modes can be at any time to enable / disable.
As already explained at the beginning, my mod packet is called ModSoup a merging of many small modifications other modders who work with TMO_RSRDC_OTC and harmony.
The aim of this package is to move the game a little more towards realism.
Hope my comments help.
