Cheats not working - no off/off switch, just code's description!
Posted: Fri Oct 02, 2020 6:50 am
I'm using negaMAME (0.244.0-1, based on MAME 0.224.0) with Negatron EXTERNAL frontend (it was made in mind for that variant) and I managed to figure out through intuitive guessing...and filling in dots from other sources other guesses about syntax of cheat.simple:
and output.json. Even though I could decipher the first of two lines for Sonic CD, I could not entirely decipher the - what does "40000000" and "FFFFFFFF" mean in those "fields-or-whatever"? I got luck with THAT game 
as far as getting those "fields" right, but apparently not on Hook (for Sega CD also BTW):
Specifically I got error after closing negaMAME (cheat script error: missing region :segacd:prgram) because I could see description under tab-called main menu-->plugins-->cheat... 
but could not turn it on or off...like it was only parsing description not toggle switch! Is it because the "40000000" and "FFFFFFFF"? 
At least tell me what those mean. 
Sonic CD code has on/off toggle switch still (hint from output.json):
