Megathread Fix | R Roms

The R ROMs megathread is a comprehensive discussion thread that compiles information and resources related to R ROMs, which are customized versions of the R programming language. These ROMs are designed to provide users with alternative interfaces, additional features, and improved performance. The megathread aims to serve as a centralized hub for users to access and discuss various R ROMs.

The primary "feature" of the is its role as a curated, centralized repository of direct links to safely download video game ROMs, ISOs, and BIOS files for historical preservation . It is maintained by the r/Roms community and hosted on platforms like GitHub to provide a more reliable alternative to ad-filled or malicious third-party ROM sites. Key Functional Features

The community prioritizes "No-Intro" and "Redump" naming conventions. These groups catalog games by verifying that the digital copy is an exact, byte-for-byte match to the original physical cartridge or disc. r roms megathread

Certain consoles (like the PlayStation 2, Sega Saturn, and Dreamcast) require system firmware files called BIOS to run. The megathread hosts a dedicated "Miscellaneous" section where these essential system files can be safely acquired.

For retro gaming enthusiasts, finding a reliable, virus-free source for classic games can feel like navigating a minefield. Malicious pop-ups, broken download links, and disguised executable files plague many ROM websites. Fortunately, the Reddit community established a definitive solution: the r/roms megathread.

Heroes 3 random map generator

Maybe someone knows good RMG for Heroes 3? This one which integrated in Heroes 3 is not good ... I always create a map with 5+ dragon utopias and 10+ towns even on large 2 layer map with only 5 players and sometimes no connection to other players so I must quit playing that map.

It depends on what kind of map you're after. Most games are played on resource rich maps like Jebus.

http://www.heroes-iii.com/ has a few templates I suggest you try.
Go to Downloads r roms megathread Maps r roms megathread Random Templates and then follow the instructions. r roms megathread

Randomly generating a good Homm map is going to be quite complex.

You have pathing issues and balance issues...

Just google: heroes 3 random template

I think for 2v2 or 1v1v1v1 Vortex is best if you want good guards between players and not too much resources, and for 1v1 Nostalgia XXL same reason

The maps are saved there only if you create a random map in game. You need to start a game with a random map, and it should be saved in that folder after that.

H3 RMG alternative

Hi

I'm creating an alternative random map generator for Heroes 3.
Features:
- templates with much more control of what is generated resulting in more predictable and balanced maps
- allows to customize generated doodad and creatures to create more thematic maps
Limitations:
- no water or underground can currently be generated
- max 1 town/castle per zone

Current version available here:
[url=http://www.frozenspire.com/MapGenerator/Index.html]Map Generator[/url]

Cheers

Please try to create some maps using the 'SunSpire' template and give me your opinion about them.

You can also try to create your own templates.
They will be stored on server and anyone can use them.

If you run into trouble don't hesitate and ask.

Thank you

Jluil, thank you for such a tool!

To be honest, if I had an RNG that is reliably generates a map without bugs (unreachable objects, misaligned guards) that would be enough.

Also, in your tool, can I load existing template from rng.txt file?

Also, are you writing your own tool or you disassembled HOMM3 tool and patching it? Can you share source code so I could play with it? :-)

Hi

It was written from scratch.
I started around a year ago when a friend of mine complained that the h3 rng generates bad maps.
The problem with the original rmg is not only that it often generates faulty maps = misplaced guards, blocked castles, no passage... but also that there is lack of control about what is generated.
You see in the original templates you can only set a value(min/max) that represents how precious objects can be generated there.
This can result in generating dragon utopia and dragon fly hives for one player while the other player gets rubbish.
I was curious if I was able to do better.
I designed custom templates with rich setting capabilities and a GUI to make it easier to create them.
Unfortunatelly old templates are not compatible with the new ones.
The generator itself tests for broken maps and tries to fix the issues. If the issues persist the map is regenerated a new.
Therefore it should always generate a good map.

Although I understand it's not super easy I would like to encourage people to create their own templates.
If you need any help just ask.

Atm the codes are not for public but if more people start using it I might delegate the project responsibility to a dedicated team.

Btw are you a programmer?

The templates are in json format and more-less represent what you edit in the online template editor.
You can see json representation of SunSpire template here:
