I ported my TI83+ asm Castlevania game to PC!
« on: October 28, 2020, 10:36:15 am »
Hi everyone! It's been a while since I posted here. In fact it's been so long (about 13 years) that my account was deactivated and I had to create a new one  ;D

Does anyone remember Castlevania: Prelude of Chaos? It's a small adventure game that I programmed in assembly for TI82/83/83+. You play Simon Belmont and your goal is to destroy Dracula. Travel the land to defeat his army of fiends, upgrade you whip and buy new weapons, fight bosses and discover secrets!

Anyway during the recent lockdown I decided to port this game to PC as a pet project. It was a very fun thing to do! Basically I wrote a small interpreter in C with SDL, hooked my own implementation of system calls, added keyboard & game controller support, made a save system and so on. Oh and I also composed a brand new soundtrack that I'm quite proud of :)

The game can be downloaded on my itch.io page and it's still totally free!

Hope you enjoy!

It's fun to come back here after all these years, and I'd like to thank the community as a whole because it played a huge part in why I got into the video game industry in the first place. Keep rocking!

It would be very interesting to see a write-up of how you went about "porting" the game. It could be useful for helping others also "port" their games.

What did you use to create the soundtracks?

I wanted to write an article but honestly I'm kinda lazy about it... Maybe for the next lockdown haha.

The soundtrack was created in Reaper with a NES VST by Matt Montag. Link

I'd be happy to read it when/if you get around to writing it :)

That's definitively something I need to try! I remember this game and I thought it was pretty great. I no longer have a regular 83+/84+ so I can't play the original, so I'll download the PC version and give it a try soon. :)

I also followed you on Soundcloud
In case you are wondering where I went, I left Omni back in 2015 to form CodeWalrus due to various reasons explained back then, but I stopped calc dev in 2016 and am now mostly active on the CW Discord server at https://discord.gg/cuZcfcF
