Interesting. And just when someone was talking about making a GUI for my speedhacker program... I can't seem to find a copy of this program to download so I can't test it. I wonder if it supports -R/W... from the looks of the screenshot and the thread discussion, it looks like the answer is "no, this is +R/W only", but I can't be sure until I get my hands on a test version. Interesting, though.
*Edit: I had a test version of it sent to me, and a test version was later also posted in the forum linked to above... in case people were curious about this new tool...
-) It doesn't support -R and -RW.
-) Uses hard-coded addressing (tested it out by shifting the table over by one byte)... as a result, it doesn't work on EXE files (failed to read the table when I fed it GS08.exe, US0A.exe, and US0F.exe)
-) It doesn't allow fine manipulation of speed codes.
+) But it is easier to use and probably a little less intimidating than my command-line program. Might be good for newbies who don't have the 812 (and thus are probably less likely to want to hack -R/W codes in the first place).
*Edit #2: My tool now has a GUI.
