Just testing, I'm not promising this will make it (also, too big to upload onto Le Weekee™).
Announcing a "new" project!
Spoiler: Video's description
That's right, it's Score Rush again. I told myself that the time I learn how to render text on the Mega Drive would be the time I remaster Sonic 1 - Score Rush, as there's a lot of nifty features I wanted to have, but could only implement with that know-how. And that time has finally come.
I decided that, instead of just using the "PRESS START BUTTON" font to display "SCORE RUSH" on the title screen, I'd make something fancier. It was not terribly easy to code in, and I was afraid of lacking sufficient VRAM, but luckily, Green Hill's background was far enough into VRAM for me to replace a good portion of the foreground art with the new "SCORE RUSH" emblem I made. I must say, I'm really proud of how it came out, despite the amount of vertical screen estate occupied by the Title Screen on its own.
Big thanks to MunchJrGames, Slick-Nick and Dr-Luxcario for their work on the Sonic 1 emblem font sprite sheet! Go check it out here.
As for release dates, Score Rush shouldn't take too long to develop. I'm pushing for a June release, but I guarantee nothing.
Also, for the time being, I will be putting most of my focus on Score Rush, therefore, I'm putting Sonic Magnified's development on hold.
At some point I was expecting karamelldansen to pop up.
I've been working on-and-off on a Mega Drive emulator since September, and I've just implemented YM2612 emulation.
I've written a blog post detailing the process of adding this, which you can read here. I've also documented other aspects of developing the emulator, such as the VDP's Interlace Mode 2 and Shadow/Highlight mode. You can find a list of my emulator-related blog posts here.
Nothing has changed much since a year ago, but here's an airship.
Also debating if it's worth revamping the entire foreground, keep it, or redo everything like a drug addict, so just incase:

I think it looks good but maybe try some different palettes out, no reason it has to be Spring Yard 2 so literally. The homage would still be apparent but a different colour scheme might be more fresh.
This is a fun amalgamation of multiple projects of mine: this is my Mega Drive emulator running my Sound Test homebrew (unreleased) running my Sonic 2 Clone Driver v2 running my custom two-channel DAC driver. Now all I have to do is get my homebrew to build with my assembler (also unreleased) and we'll have the very epitome of NIH syndrome.
Speaking of the emulator, it now has partial Z80 emulation, allowing the music's drums to finally be heard.
Been messing around with Sega CD boot mode 1 some. Made a "mode 7" graphics and Ricoh PCM streaming demo a while ago.
Download is in the description. Works on real hardware, too.
Been working on and off on it and making a full on driver for it that can play back sequence data.
I'm so interested on someone using the ricoh chip in conjunction with the 2612... that's arcade level of sound right there.
Would be possible and interesting, but there's no YM2612 being utilized in either video.
Something I've toggled around with and got working in VERY rough condition (as clearly shown with some graphics :P).
Fun fact: Sonic 2 actually has a separate 2 player level order routine if you deactivate the VS results. It consists of the three levels and then goes back to the SEGA screen.
Oh yeah I didn't meant to mean the YM part for your video specifically. Sorry if it sounded like that.
But since we're here... do you have plans to do something with that on the future, or SCD is such of an interface mess that it's not realistically feasible?
I can make it work. The Genesis side can send an interrupt request towards the CD side whenever.
My emulator finally gives the Z80 instructions their proper durations, so DAC samples now play at the correct speed. With this, some games are now fully emulated with no missing or broken features. This may be the last update here for a while.
Showcasing the new character select screen, and some Blaze gameplay.
As a side note...
If knowledgeable people wish to help with this project, feel free to contact me through discord. You can find me on the Sonic Retro, SSRG or MDDC discord servers, if you need to. I am looking for sprite artist, level art artist, musicians and pretty much anybody who is more experienced in 68K assembly code. I'd like to get a demo of this out at some point, but with just myself doing a bulk of the work and not having as much free time as I wish I could dedicate to it, progress is pretty slow.
