Yes, it would seem the .xex versions won't/can't allow customization of gameplay parameters.
I tried to make a longer game earlier in the week, but I didn't get it to make a difference so either I didn't do it right, the instructions are wrong or the dumped file does not support it.
Grabbed the attached .atr from atarimania and checked it in emulation; just started it up to see if it works and it allows for time and date to be adjusted as well as speed.
Using/keeping existing high scores from .xex file(s) C'est La Vie play seems like the easiest and most uniform way for HSC Season 15 Round 9 to proceed; that is, I am not sure if we want/need to throw a curve into the mix by adding customization of gameplay date, time and speed to the current round but I thought some might like to try using carlsson's detailed game instructions fully with C'est La Vie.
I need to get cracking and go try to rack up some big green myself but $2000+
...I am still trying to crack $250+
