Cheats not working - no off/off switch, just code's description!

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:

Code: Select all

(cheat_simple.lua : -- ram/rom cheat format: <set name>,<cputag|regiontag>,<hex offset>,<b|w|d|q - size>,<hex value>,<desc> -- only program address space is supported, comments are prepended with ; -- size is b - u8, w - u16, d - u32, q - u64 --")
and output.json. Even though I could decipher the first of two lines for Sonic CD, I could not entirely decipher the

Code: Select all

":segacd:40000000:FF1516:00000000:FFFFFFFF:-----SONIC CD----- Infinite Time"
- what does "40000000" and "FFFFFFFF" mean in those "fields-or-whatever"? I got luck with THAT game ;) :D :) as far as getting those "fields" right, but apparently not on Hook (for Sega CD also BTW):

Code: Select all

segacd,:segacd:prgram,5E2A8,b,2D,-----HOOK----- Infinite Time :segacd:40000000:5E2A8:0000002D:FFFFFFFF:-----HOOK----- Infinite Time segacd,:segacd:prgram,5E29D,b,80,-----HOOK----- Infinite Fly Meter :segacd:40000000:5E29D:00000080:FFFFFFFF:-----HOOK----- Infinite Fly Meter
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... :cry: but could not turn it on or off...like it was only parsing description not toggle switch! Is it because the "40000000" and "FFFFFFFF"? :idea: At least tell me what those mean. :| Sonic CD code has on/off toggle switch still (hint from output.json):

Code: Select all

"[{ "space":{ "cpup":{ "tag":":maincpu", "type":"program" } }, "script":{ "run":" cpup:write_u8(16717078,0, true)" }, "desc":"-----SONIC CD----- Infinite Time\r" },{ "region":{ "rom":":segacd:prgram" }, "script":{ "on":"\t\t\taddrs = {\n\t\t\t{addr = 385704, val = 45},\n--flag\n\t\t\t}\n\t\t\ton = true\n\t\t\tfor k, v in pairs(addrs) do\n\t\t\t\tv.save = rom:read_u8(v.addr)\n\t\t\t\trom:write_u8(v.addr, v.val)\n\t\t\tend", "off":"\t\t\tif on then\n\t\t\t\tfor k, v in pairs(addrs) do\n\t\t\t\t\trom:write_u8(v.addr, v.save)\n\t\t\t\tend\n\t\t\tend" }, "desc":"-----HOOK----- Infinite Time\r" },{ "region":{ "rom":":segacd:prgram" }, "script":{ "on":"\t\t\taddrs = {\n\t\t\t{addr = 385693, val = 128},\n--flag\n\t\t\t}\n\t\t\ton = true\n\t\t\tfor k, v in pairs(addrs) do\n\t\t\t\tv.save = rom:read_u8(v.addr)\n\t\t\t\trom:write_u8(v.addr, v.val)\n\t\t\tend", "off":"\t\t\tif on then\n\t\t\t\tfor k, v in pairs(addrs) do\n\t\t\t\t\trom:write_u8(v.addr, v.save)\n\t\t\t\tend\n\t\t\tend" }, "desc":"-----HOOK----- Infinite Fly Meter\r" }]"

If you need to figure out how to add cheats not already made by Pusgy, you can head to http://www.mamecheat.co.uk/forums/ MAME itself has no control over its creation.
