[Hybrid]

ahh makes sense i forgot about the export tool. i've been here long before that even existed

[terpsfan101]

In other words, if the database were able to export all the modifiers with their descriptions, I would go back and modify my codes in the format suggested by Hybrid.

[terpsfan101]

Why would I care about boosting my "code count?" I'm posting them in a format that is compatible with PAT cheat files that Kega Fusion and Gens emulator uses. And I would prefer posting them in the database this way because it makes them easier for people to export the codes.

[Hybrid]

...etc
plus you know with these types of codes you can add the values together to enable multiple cheats eg
00CC15:07 is quick hands ,Max Power and Goal Tending

putting separate codes for each modifier is just a way to just unnecessarily boost up your code count. it makes alot of work for you and makes the cheats harder to find
i've even started using modifier format for Game Genie Codes

heres some codes i made for a hombrew game called fix it felix jr
