proof-of-concept custom server for SEGA SPLASH! GOLF

SplashSrv

A proof-of-concept server for SEGA SPLASH! GOLF

⚠️ This project is not affiliated with or endorsed by SEGA.

⛔️ This server is very incomplete and experimental. Don't expect to get a realistic gameplay experience out of it; there are lots of missing features. The multiplayer code is not production-ready.

How To Run

I developed and tested this project with Rust 1.72 on an ARM MacBook, but newer versions should also work.

• Modify the ip_address in src/login_server.rs to point to the IP/hostname of the machine running the server
  • This is necessary to get past the Server Select screen
• Run with cargo run
• Create an account
  • Open the SQLite console with sqlite3 splashsrv.db
  • Enter: INSERT INTO accounts (login_id, password) VALUES ("test", "asdf");
• Run the game using SplashHack
  • Log in using ID test, password asdf (or whatever else you put into the database!)
• Enjoy 2008's finest Pangya clone!

Further Work

I don't expect to go further with this project as I'm about to start a new job, and I wanted to wrap up SplashSrv and publish something before then, even if it's very incomplete. With that in mind, here's a list of the improvements I wanted to make.

• Better dev practices in the server code
  • Read configuration (e.g. the server hostname) from a file or environment variable
  • Hash passwords instead of storing them as plain-text in the database
  • Include some tests
  • Double-check packet definitions in packets/mod.rs
    • Some packets have incorrect bitfield definitions because I misunderstood how Deku handles bitfields, relative to Visual C++
  • Implement the various kinds of ping packets
• Complete user management and social features
  • Chat (SEND_MESSAGE)
  • Friends list and block list
  • Mail
  • Delivery
  • User titles
  • Colours (ORD_COLOR_ELEMENT and the like)
• Complete lobby/room management
  • Implement packet 24 (exiting a room)
  • Figure out and implement retiring from a game
  • Correctly remove players from a room when they disconnect
  • Allow room settings to be updated
  • Allow room leadership to be transferred
  • Invites
  • Figure out what happens when a room is empty (does it get deleted?)
• Improve the shop system
  • Figure out more realistic prices for items
  • Add all the equippable items to the shop
  • Remove invalid/incomplete items from the shop
  • Implement buying salon items
  • Implement buying new characters
  • Implement buying items with tickets
  • Implement renting caddies
  • Do something with the recycling shop
• Improve/complete gameplay
  • Use the room parameters when generating an ORD_GAMESTART packet
    • Allow different courses to be played
    • Pick random holes, weather, etc.
  • Implement item usage
  • Implement caddy usage
  • Implement 'growth' (gaining experience and levels)
  • Implement quick matching (ranked 1v1 battles)
  • Store and track the different kinds of records
  • Test and fix Competition Mode
