That also explains the issues with “Fast H40” and “Fast H32” VDP register hacking… to get satisfactory results with an offspec signal, you’d probably need to install some kind of timebase corrector...

Does this wrapper work for the games that were developed for the Diamond Edge 3D?

I want to see Sonic hacks made for the Victor WonderMega (with its MIDI and DSP capabilities), the Pioneer LaserActive (even if it means making a LaserDisc from scratch somehow), the Mega...

Replace more things?

Does "Blue Sphere" on its own have any problems with the 68010 and/or an overclock?

Some people still use CRTs and rear-projection TVs.


Screensavers also have a certain aesthetic, not to mention amusement factor.

I personally grew up around screensavers, so not having them...

An idea popped into my head a while back, and again recently, regarding the idea of making screensavers for retro consoles. For example, making one for the MD or 32X in the form of a lock-on...

Also on the subject of 68k CPU modding… if you attached a PMMU (paged memory management unit), such as the 68541 or slightly newer 68551, do you think it would actually hurt performance, or only when...

I don't suppose Ghidra has a Sega Genesis plugin yet... ^.^;

Some Mega CD games have been tested, but it's never been clear whether it was the 68k on the MD side or on the CD side that was replaced.

The game was built almost entirely in C, so it can be decompiled and recompiled.
As for the whole Emulator / MiSTer thing... I want to make something that can run on real (and preferably un-modded)...

Yeah, but... I'm solely looking at compatibility. Shells can be redone.

Hello all! I'll get straight to the point: I want to take part in developing a hack to optimize Sonic Spinball so that it actually runs at a decent framerate on stock hardware, and preferably does so...

Some 7800 cartridges actually contained the sound chip from the 5200.

Darn.

Well, back to testing I guess.
It's been previously established that Sonic 2 runs fine on the 68010 (though special stages are a litte fast), while Sonic & Knuckles doesn't run at all. But...

Welp. That rules out SH-2 overclock compatibility.

I wonder if a 3DO controller will work on a Mega Drive

I’m really just trying to eliminate every performance bottleneck I possibly can. A hypothetical “what could have been” sort of system.

I mean, look at the Pioneer LaserActive. That thing cost over...

Darn.

Well, the YM2612 has a couple of hardware interrupts that are supposed to tell the 68K and Z80 when it’s busy versus when it’s free, but in all of Sega’s infinite wisdom they never wired...

Hypothetically speaking… I wonder what frequency you’d need to set the master clock to in order to get 60 Hz output while running it in “50 Hz PAL” mode.

Does any of the game logic run on the SH-2’s, or just the graphics rendering?

The eZ80 supports internal flash memory, up to 256 kilobytes. Hypothetically, you could program a table into that flash memory, so that with every instruction it completes, it must wait a certain...

What sorts of mods are generally recommended for newcomers to the hardware modding scene?

Me: *Boots Mickey Mania on a modded PAL Mega Drive.*
Game: “This game is only to be played on an NTSC Mega Drive system.”
Me: *Flips the 60 Hz switch.*
Game: “Oh. This console has somehow become...

Ye gods, my plans are ruined! D:
