It seems that several old rom sets exist over the world. To the above mentionned
sets (1/86, 11/85), I want to add french old rom set: 4/24/86.

So, I have hacked the already-hacked version to make it work on french old and
new rom. 

What you have to do if STARTGEM.PRG (the last one) do not work with your TOS
version:
 
1) Using TEMPLMON, look at locations fc0018-fc001b. You should see the 
date of your rom set.

2) using a file patch (e.g., mutil.prg), modify STARTGEM.PRG. Look for 
"11201985" (near 0x200 after the beginning of the file)
and replace with your date.

3) run the new startgem. 

I have found these infos using DIS2MWC and TEMPLMON, two P.D. software.
Thanks netlanders! -)
