Sonic games and frame rate
Post Posted: Sun May 26, 2013 5:07 pm
Does anyone else have trouble? It seems that in these games when I jump grabbing rings as well as having enemies around me it just starts to lag badly. It seems to be the worst on Sonic Chaos however. I saw a video of the SMS overclocked at 4.4 MHz, but it causes Sonic's sprite to glitch a bit. Is there any way to overclock it without any sprite glitch with a model 1? Also, does it really lag much for you guys? I don't remember it being so laggy.

Sonic Chaos is pretty bad, but the first two are not so awful. Overclocking is tricky because the video chip's timings get messed up, there are technical ways to overcome this but I don't think anyone ever did it for the Master System.

The Power Base Converter wouldn't make a difference right?

I just realized something..

When I play Sonic games that are PAL on the Master Everdrive, the music and pace is like it would be at 50hz. Why is this? I think this is why the games seem slow so, because on Youtube when people play Sonic games at 60hz the music is much faster and it seems to not lag much.

Shouldn't they be playing this fast on my SMS 1 NTSC console?

there is something off with that video or mod, Sonic 2 doesn't run that fast on my NTSC systems, in fact its not as fast on my pal consoles either

That's strange, I wonder if there were PAL-optimized copies of Sonic 2. I used to own a copy of Sonic 2 and it definitely didn't play that fast on my NTSC system.

Well, I'm being told that if I have a 50/60 Hz switch regardless of mine already being an NTSC..it should give it that speed. I'm confirming it with someone who might mod my other SMS NTSC model 1. Perhaps someone else on here can confirm this...ik this switch mod sort of "overclocks" the system a bit. This would be great, especially for Sonic Chaos.

I might be that the game detects PAL/NTSC when it starts and then he changes it on the fly (making the game play faster when switching from PAL to NTSC).

I have a pal master system 1 with a 50/60hz mod that does not play at that speed.

Sonic 2 checks the speed at boot. Both Genesis/Megadrive or Master System version.

Switch while running from 50hz to 60hz, music will be too fast.

So in other words, the game will already have to be running in 50 Hz before I see a speed increase by switching it to 60 Hz?

Yes, the game detects the system speed on startup. If it detects 50Hz and you later switch to 60, it'll be too fast. Note that this also affects some timings so it may also make the game slow down in places or maybe even glitch out; but that's pretty unlikely (only if they programmed it to do more work at 50Hz).

Right. Feature is much more widely associated with the 16bit game.

Well I'm currently having the switch installed on my other SMS NTSC model 1, so let's hope it works =P

You'll need a compatible TV. And likely color fix if using composite/RF.
NTSC encoding at 50hz is non-standard.

Well I'm having s-video installed as well if that helps. I wouldn't play at 50 Hz. I'm honestly confused by the whole thing. I just simply want the speed increase similar to most 50/60 Hz PAL SMS2 models being switching to 60 Hz during gameplay.

I played Sonic 2 a lot... Both SMD and SMS versions.

But that's strange... If I run Sonic 2 ROM with Meka, the game is always too fast, and I have to slow down the emulation to 50MHz. I always thought there's a specific brazilian version for the brazilian market, and the ROM I'm using is from a PAL game. Now I know about the game's speed check, and not a different game for each region.

But why the game always check Meka as a 50MHz system, even if I configure the emulator's region to Japan or the emulator's speed?

Yeah 50hz/60hz is not the same thing as English/Japanese.

They're separate settings on Master System or Genesis, each console should have 4 potential regions.

Perhaps meka doesn't emulate Sonic 2 correctly? It's obviously not behavior either an unmodified American or European model would have.
