retrorgb.com/castlevania-... - Thanks @retrorgb.com for the write up! I'm really proud of this port of Castlevania II, it's got so many great features, and was both a challenge and a lot of fun to port!

Let's talk about memmaker and configuring our autoexec.bat files!

Picking 9 is way too hard. And would probably be different if I did it again. Made with my9games.com

Links to the port are in my pinned post. Both archive.org and mega.nz builds have been updated. And as always, if anyone finds any issues, please let me know.

I was finally able to dig into why my Castlevania II SNES port's Save Menu was locking up only in Snes9x. (For those curious, it appears to be something related to how it handles reading the $4210 register).

I've updated my port to version 1.2 which should now fully function in Snes9x.

Well shoot. I do need some more snes boards...

Incredible. I am going to take a breath and marvel at the fact that Magic: The Gathering players have just raised $75,000 for @translifeline.org in a little over 8 hours.

I've been spending some time the last few days collaborating with Fiuke Bnuy on this update to my Castlevania port. I think it's going to be really cool if we can pull it off. All of the tilework is done by Fiuke, I've just been providing scaffolding and support on the romhack.

Here's an interview with Video Game History Foundation's Frank, where we talk about their Sega Channel finds, the NES's launch and lots of other stuff. Just search any podcast app for "RetroRGB Cifaldi", or check out the main post here: https://retrorgb.com/interview-with-vghfs-frank-cifaldi.html

This list is my official uploads:

The June 23rd one appears to be uploaded by someone else, and is marked as Spanish. I'm not sure if they just re-uploaded it or actually translated it.

FYI, seems like the in-game save menu in Castlevania II is not compatible with Snes9x. No idea why since it's fine on original hardware. Passwords should still work.

No plans for any other major features, enjoy!

Honestly I can't believe I didn't realize how much stuff you walk behind in the NES game. I've speedran that game, I made the randomizer, I've played it hundreds of times. I guess my eyes just ignored that ><

And now a fix for my latest game! I missed the knockback sound effect (actually all dcpm sfx, and am going to go back and see if CV2 uses any more). I've rectified the situation and updated both archive.org and mega.nz locations with the latest file. Music disabled in this clip to demonstrate.

30.11.2025 01:20 ๐Ÿ‘ 25 ๐Ÿ” 4 ๐Ÿ’ฌ 3 ๐Ÿ“Œ 0

mega.nz and archive.org have been updated with the new versions. I briefly tested all of these, and they all seem good, but as always if anyone finds any issues, please let me know =D

Aside from the controller support, a few games I tweaked the audio engine to improve some sound effects.

For LifeForce I updated the image in the options screen.

And finally, in Kid Icarus I finally fixed the bug where sprites weren't properly going behind BG tiles:

I just finished uploading new versions of my first 8 ports (everything up to Castlevania 1/2).

Most of the games got only a minor change in how I read the joypad data in order to support more modern controllers like the Limted Run Games Rumble controller

I'll outline other changes in replies here!

yay! enjoy!

should support it fine. I've used an FXPak for all my save testing.

Make sure your SD card isn't locked, since it would need to write to a new SRAM file for it. But if other games are saving that probably isn't it. That's about the only thing I could think of that would cause it =(

Hitting select while on the inventory should bring up the save menu. What platform are you playing on?

In general yeah, and I try to build all my games to fit on standard 4MB HiRom boards ( @mousebitelabs.bsky.social has some great ones that I use) without any special chips.

If you like what I do, and want to buy me a Mocha, feel free to toss me a tip here: ko-fi.com/rumbleminze

Note that this wouldn't support the MSU-1 options for obvious reasons.
