Huge shoutouts to Bizqwit for original NES hack, it make this game so much more polished and approachable.

I'll drop some details in replies here; the hack is available here:

@displacedgamers.bsky.social - you might appreciate this. This is the unmodified NES Castlevania II game, bankswitching 108 times in one frame. Maybe if you get a free weekend you can tell me why in the world it does this.

Additionally, another cool romhack feature that I just finished is the map that's accessible when you pres Select, this map was available in the FDS manual, and maybe could help make sense of the crazy world Simon is in:

I've just put the last finishing touches on a Beta version of Castlevania II for the SNES. A big part of the last couple weeks were getting this intro scene from the Enhanced Romhack working on the SNES:

Another post on Castlevania II Progress!

I'm in the middle of tackling attributes, which control the palettes the BG tiles use. It's one of the more complicated undertakings in the ports, but it's coming along nicely! Here's a couple minutes of footage of the beginning of the game.

Ok, maybe someone knows more about this than me. But why does Castlevania II on the FDS have so much English text? The prologue and the ending are both entirely in English. Is that not odd? Did Japanese children know enough English to read this?

The rest of the game is all in Japanese.

I've been playing through my FDS version of Castlevania II, and the music is just a joy (apologies for the 10s of FDS loading at the beginning)

Completed a full playthrough on my Castlevania II port. This is a good milestone, it means the game logic is solid. The only issues I encountered were either related to the romhack enhancements, or things I know I haven't done yet (like music/palettes/bank switching)

Got some great labels for my physical carts of my ports from @artisticpixels.bsky.social and @arielaces.bsky.social

I knew this part of the port would be hairy, and there's still some quirks to work out, but the SRAM saving/loading is working!

@displacedgamers.bsky.social this one's for you. first screen of Rover Mansion comparison. NES has lots of noticeable lag, the early version of my SNES port is buttery smooth. Also, sprite palettes are all updated, and BG tile palettes are updated, but everything is using palette 0.

Castlevania II Enhanced progress update! Getting into the main game now, and while palettes aren't ported yet, the game is surprisingly playable. Lots more to do yet!

After a bit of a break, I've begun work in earnest on my next project! This one is a bit different, and I'm hoping to leverage the amazing work that @bisqwit.bsky.social has done on Castlevania II amazing improvements. I'll be porting their romhack version instead of the original game.

Not enough people talk about Phantasy Star 4 as one of the great 16 bit RPGs. But I just played through it this weekend and it's great! fast pacing, cool characters, good story. And if you played the earlier games (especially 1 & 2) there's tons of fan service that doesn't feel shoe-horned in.

My @cosam-the-great.bsky.social Neptune board up and running! Shoutouts to the @retrorgb.bsky.social and @dubesinhower.bsky.social Discords for some troubleshooting at the end. By far the hardest project I've taken on. It's a shame tariffs have put a Neptune shell out of the budget :(
August 7, 2025 at 2:27 AM
Works great 👍

1 SNES cart with both my Double Dragon and Double Dragon II ports on it! @mousebitelabs.bsky.social it works great! Any suggestions on a switch to expose outside the case to make it easier to switch games?

So disabling the sprite shuffling is trivial, but since the sprites aren't logically ordered, it just results in some Simon sprites being always overwritten by things like the torches:

We'd have to rewrite a bunch of logic to force Simon sprites to the front of the sprite list.

It's very oddly satisfying to watch in the Mesen sprite viewer
