What does +x mean in a trainer/table name?

[dstarfire]

Seen a lot of trainers and cheat tables over the years labelled simply as (name of game)+3, (game)+5, etc. (e.g. "Halo +3 trainer"). Often this is accompanied by a list of features (e.g. infinite health, inf. ammo, etc.), but sometimes it's not, as though that +x somehow defines some basic features.

So, what the heck does this +x mean?

Number of options/cheats

It comes from the old bootleg days when ROM images would come prepacked with a trainer.

So a release would be something like Super Mario 3 (USA) +4, meaning it came with 4 cheats, which were usually activated during the cracktro that was presented upon booting the bootleg image.

It's like when you hear kids say day0 or binz. What used to happen in the Apple ][e days, was someone would have a ware, and they'd take 2 or 3 days to crack it, so if it took 3 days from release, it would be a 3 day ware. Some people were a boss, and would have a day 1 ware, and if you somehow were a master theif and got it before release, it was considered a day 0 ware. Now people use it for fucking everything. I even saw RE7's crack being touted as a Day0, even though it took them 6 or something days to crack...

Although, granted, people are actually still using the +x term correctly.
