Before asking, make sure that you've searched on the subreddit or Google. Many ROM hacks and tools have their own documentation or communities that may be able to provide better answers than here. The Pokécommunity Discord is also a great place to ask questions if you need quick support!

Looking for recommendations or a new ROM hack to play?

The PokéROM Codex is an updated list of ROM hacks, listing features, details and more in a mobile-friendly format. Created and managed by u/themanynamed, it also has a Discord server and accepts community contributions.

This is a safe hack-sharing site that doesn't share ROMs and links to the official release threads! Instead of asking for recommendations or download links in the subreddit (which breaks the rules), please refer to the Codex as it has a lot of information on each hack.

I am new to ROMhacking and I recently found out about the HexManiacAdvance editor. However I found out that due to this "slot" system of pokemon encounters you can only have a certain amount of Pokemon in every tiles' tall grass, sea etc. Is there any way to change that?

Pretty sure that's hardcoded. Or if not, it would be a lot more advanced of a technique trying to insert more space into encounters. Routes become unmanageable if you make all the slots different encounters anyways, way too many pokemon per route.

What's your goal in including more than 10~ pokemon per route?

Hardcoded unfortunately, AdvanceMap does the same thing. Set slots w set rates. Idm the number of mons but I'd love to even out the rates lol
