The infinite energy codes for the SF2 games do what they say, but they also make the player pretty much unhittable. This makes them useless for practical training. If you apply some conditionals they behave as intended: [sf2] <cheat desc="Infinite Energy PL1"> <script state="run"...

Here's some timer-related codes. I found these working on something else , no point in not sharing. [sf2hf] <cheat desc="Select Speed"> <parameter> <item value="0x00">No frameskip (like SF2CE)</item> <item value="0xFF">Maximum frameskip (double speed)</item> </parameter...

If someone out there wants to get into making ROM codes, this would be a nice starter project.

Thanks.

Update: http://pastey.net/149504 (diff) These now remove the HUD for the sf2 games, sfa, dstlk, nwarr and cybots. Also, the codes for those plus sfa2 & sfz2al were dropping some desirable sprites, so I took out the minimal amount and left comments telling what stage to pick to avoid the rest. Th...

Got some codes to remove the backgrounds for some CPS1/CPS2/NeoGeo games. These are for sprite ripping and related things. [sf2], [sf2ce], [sf2hf], [ssf2], [ssf2t], [hsf2], [sfa], [sfa2], [sfz2al], [sfa3], [dstlk], [nwarr], [vsav], [vhunt2], [vsav2], [ringdest], [cybots], [sgemf], [xmcota] , [msh] ,...

Verified working in some of them:

sf2acc
sf2ce
sf2ceea
sf2dkot2
sf2ebbl
sf2ee
sf2hfj
sf2hfu
sf2j
sf2koryu
sf2m4
sf2qp1
sf2rb
sf2red
sf2thndr
sf2uk
sf2v004
sf2yyc

But there's no sound for sf2mdt anyway.

I've found this doesn't always make silence fast enough. Here is a better method that alters the program code: <cheat desc="No Background Music"> <script state="on"> <action>temp0=audiocpu.rd@00AA</action> <action>temp1=audiocpu.rd@025A</action> </script> <script state="run&...

People who want a RAM search should try MAME-rr, which is being maintained by my friend mz: http://code.google.com/p/mame-rr/ It has the same ram search as the other tasvideos emulators . Plus Lua. http://img844.imageshack.us/img844/6384/ramsearch.png And of course it has the debugger as well. So go...

Here's a set of codes in FBA format for [sf2], [sf2ce], [sf2hf]. Only the two bytes at D048 control the music, but the first notes will stick forever unless you find and kill them also. The notes are found in a range from D300-D400 but as you can see only half those bytes have to be zeroed. cheat &q...

You can find those in an FBA cheat collection which seems to be offline now. Here's a mirror: http://www.mediafire.com/file/mxdwmg2ct71k9xz/fbcheat0294d.zip <cheat desc="Max level (Partner) PL1"> <script state="run"> <action>maincpu.pb@FFB7A5=0E</action> </script> </cheat> <cheat...

These are formatted to work with mednafen . I tried testing in MESS but it won't take my bios file. :-?

Thanks, that's very fastidious.

By the way, if you were wondering what all that mutecode fuss was about, much of it was for preparing these:
