Is Perfect Blue currently unplayable? Here is what I did with hacks.lua. Note: I tried to compile it independently, and I've never written a lua script before. According to VBA, the checksum was (1481) 1481.
{
  ["crystal"] = {
    [0x8447] = {
      game = "crystal-clear",
      language = "en"
    },
  },
}

{
  ["red_blue"] = {
    (1481) = {
      game = "perfect-blue",
      language = "en"
    },
  },

Okay, I've updated the first post to version 2.4. Hacks are fully supported now, regarding headers, checksums and all of that. You can take a look at the readme in order to learn how it works now. In upcomming days I'll update the post with the steps.

@Nuive. Thanks for the update. I can run anniversary crystal with this. However, the support for this hack with these scripts is very basic. The pathfind doesn't work, and neither do the footsteps, although the latter is a minor problem. But I like how the new object locator seems to show more objects.

The pathfinder works for me, now I can finally play Perfect Blue! Their are no footsteps, but that doesn't matter since I can just count the amount of times I press buttons.

Another hack, Pokemon TPP Red Aniversery. Remember how I said how it was playable on another topic? Well, time for a real challenge...

This hack seems to be a bit harder.

@Nuive,
could you please contact me? I have a few questions regarding the german translations.

@Nuive, i didn't see that on the readme actually, i'll look at it, however pokemon coral may contain bigger maps.
Edit, now it says ready, but i have to press t to read texts, at least for pokemon coral D2.2. There is also a bug in the path finder.
2nd edit, pokemon orange goes weird, when i'm done configuring the script, i hear numbers before the text.

So I just started a playthrough of Crystal and I'm wondering, how do we actually get an idea of what the puzzles in alph look like? Unless I'm missing something? I know visually you can go round and look at them of course, but yeah.

@techmaster20: I have the same problem, when you are in the file list press p and if you don't here a Windows sound press enter, and if it sends you back to the Lua script dialog, press run. At worst, type the complete file path in the edit field, if you are familiar with that.
But still, if anyone knows how to fix it, that would be appreciated.
As for my experience with hacks:
-Roaming Red seems to work perfectly fine, didn't explor the whole game as of now but the only problem I've found is in the Pokemon Mention, on a certain floor, the path finder finds cliffs which are probably out of maps and using it makes the scripts crash. I don't know if it is different in regular Pokemon Red.
As for Red++, it seems that this problem is in the whole game, the path finder can't focus on the current map and pressing P crashes the scripts. Didn't try the hard version but I guess it may probably be the same thing. It is the same that happened when someone tried to adapt the scripts for Polished Crystal when I asked it on their discord, a year ago or so.
Again, just thought I would share my experience here in case someone would be interested in figuring stuff out.

hello, I'd just like to share this, since I just noticed that support for hacks has been added. I generated a correct map names file for TPP's pokemon crystal anniversary from its assembly code. I've been using it to play through the hack using TSP's original scripts over the last two weeks or so and the map names line up correctly so far. I just regenerated the maps file to be the same format as is expected by nuive's scripts. If someone would like to use it to add crystal anniversary rom hack support, then they can find the maps.lua file as well as the script that generated it on this branch of this github repo (master branch just contains maps file for TSP's scripts).
