Still got my Mega Drive, purchased circa 1994. Recently brought it back to life with a Level Hike (I know, apparently RAD2x is better, anyway works well enough for me) HDMI adapter (otherwise sadly it doesn't work with new digital-only TVs), the main unit and all my old games (Sonic 1 and 2, Columns, Alex Kidd in the Enchanted Castle, Wonder Boy in Monster World, Shining Force (needed new battery in cartridge for sav…

and everybody clapped

Earlier quoted context omitted.

people go through so much trouble buying expensive converters, scalers, etc. to make their old games look good on their new tv when there's plenty of old CRTs at thrift stores for maybe like 50 bucks for an excellent one with all the fancy hookups like component and everything, I don't get it. I understand CRTs aren't gonna be around forever so we should in fact be working towards future proofing but, they are around…

I just emulate. So much easier

yah but then you get dropped frames and intermittent audio popping and when the game glitches or even crashes where it would do the same on real hardware, you're left wondering if it's the emulator that's fucked up. I don't wanna have to think about any of that during my leisure hours. The game owes me a good time.

Genesis does what Nintendon't. > The lowly 68000 in the Sega doesn’t have a memory management unit required for the full Linux experience, so what’s really running here is a kernel compiled with the -nommu option. Huh... I thought Linux actually required MMUs. I was under the impression it'd never run on these old consoles because of that. Learned something new today. > A QEMU fork that emulates enough of the MegaDri…

There was no MMU in the Macintosh Classic/SE lineup which used the 68k as a CPU, but they still support the microcontroller targeted distros like uClinux. Unfortunately the tight integration with the ToolBox ROM makes it a fairly Herculean task. Microsoft bizarrely enough released Xenix for the Apple LISA as well, but that's more of a historic oddity. Similarly, Basilisk II is a very worthy emulator for Mac 68k emula…

there was another unix on the lisa as well

Very cool to see, so pointless it just had to be done. I was wondering how it was squeezed into 64KB of RAM but it uses the 4MB on the Everdrive cart. With that it makes sense, considering Linux can run on an N64 with 4MB of RAM.

RAM is hardly the only difference between the N64 and megadrive. The N64 has an MMU for one thing

in terms of running linux, yeah it kinda is. Both archs are supported by the kernel, and the kernel doesn't need an MMU if you compile it for a system without one

Streets of Rage 2 Ghouls and Ghosts Radical Rex Jurassic Park These megadrive games had great art and music and are still really enjoyable today

Comix Zone holds up well too I think.

For my American friends who may not know this: The Sega MegaDrive console from the late 80's early 90's is what we call the Sega Genesis. When I saw this post, I assumed it was some kind of optical drive or the later released Sega CD (which the rest of the world called Mega-CD). We had a lot of good times playing Street Fighter II and Sonic on this system back in the day.

I had to look it up.

I misremembered and thought it might be what we call the Master System (SG-1000 Mk III).
