I've been testing the SPC 2.5 Eliminator harness kit which provides for a way to remove the add-on card. Once I did this I was able to edit and save the Comms Configuration tab where the values are set for getting these type of TITO devices working.
However, the Bill Validation settings are fixed on Validation type as (No Validation or Secure Enhanced). However, the jurisdiction of Columbia says default validation is SYSTEM which these TITO devices need. But there is no Gamma Port option in Game Configuration for the type of game I'm using to get it working. I'm trying to get TITO working on Viridian Widescreen, not Viridian Standard (MK7 19" Narrow Screen), and don't have an MK6.
When I review the setting under the jurisdiction settings found in the Game Setup (set chip audit program) it says no options allowed for this game and that is where I'd find the Gamma Port values. It says in Comms Configuration tab that since World Base 5.07 no SPC 2.5 card is needed and as a result, no SPC 2.5 Configuration tab is found.
I've discovered that each game/theme determines what options are available for settings. The jurisdiction options for validation are the following, None, Game, System, Secure Enhanced, Sec Han D/A, Enhanced.
If ATI has made a wiring harness that removes the need for the protocol converter using only a harness kit then there must be a way to support SAS within what is available. But for some reason at the set chip screen, it says the validation is configurable in the game which it appears is the case yet those options don't appear to be offered by every game. Therefore the ony way I can see TITO working is for many of us to work together in getting Secure Enhanced working over SAS so that the functions we all enjoy now related to TITO over SYSTEM validation are an option.
Anyone interested in working on this to get it over the finish line let me know, I'm doing active research into it now, and I'm sure this was sandbared due to COVID so we'll have to pickup where the group seeking answers on this can reorganize and get it done.
