Favourite hard version hack

[jabberjabber8]

As of recent I have acquired a taste for hard version hacks
these are well known hacks or just plain roms that have had the difficulty of the games raised significantly somehow.
So far I have played:
Shiny Gold X (finished)

Spoiler:

I heard shiny gold and was hooked all ready, but this game does not really provide to much of a challenge

Pokemon emerald hard edition (bored at gym 4)

Spoiler:

I liked this game but There were to many strong pokemon available early (e.g. bulbesaur available in petalburg woods)

Pokemon fire red infernos (completion status: gym 8)

Spoiler:

This is my Favourite so far, Has all pokes available but its done quite well not throwing them anywhere, and the difficulty is drastically increased, i am struggling to beat gym 8 at the moment with a team of high level 50's

So I was wondering If anyone else knew any other hard versions and which of them is your favourite...?

Well, in the Sideshow Showcase section (Hacks Showcase > Sideshow) There are a few harder versions to things. Along with 386 / 493 / however many pokemon there are now patches. :)
