Re: Megadrive was always the answer

Well, when you're talking about making an add-on to improve the console, you probably want to throw the coprocessors into the mix (especially if you can use them to do something like the 3D in Virtua Racing). So I'd say it's not just a detail. For what's worth it, I think an extended Mega Drive with...

Re: Move text on screen

Yeah, RPGs do this by using sprites. Not worth trying to use the planes when it's a small graphic and gives more flexibility for the animation.

And the second UMDK and Mega Everdrive x7.
I don't recall any of the Mega Everdrives having an ARM CPU inside them.

Re: Need Remove All Sprites from VDP

What is shown on screen? I don't see it at screen, I see on Gens VDP sprites list (Gens > CPU > Debug > Genesis > VDP Sprites). Thank you. Errrr that's exactly what the function is supposed to do then. It doesn't matter if the table is fully cleared as long as the player doesn't see any sprites on ...

Re: Need Remove All Sprites from VDP

I was going to say something like that but then I noticed that the first sprite isn't linking back to 0 so it's possible other sprites may be still shown (the pic doesn't show far enough to tell if it ever ends up linking to some sprite that's visible).

What is shown on screen?

Re: Mega Mouse with wheel

Well, that's encouraging.

May as well point to this thread so they implement the enhancements :​P (the trial version of Arkagis Revolution does have some mouse wheel code)

Re: Mega Mouse with wheel

DO NOT TRY IT , you may end up burning something, the pin assignment isn't the same. To make that work you'd need custom firmware (since there doesn't seem to be any Mega Drive firmware available) and even then you need to be able to change which pins get VCC and GND (no idea if that adapter can ch...

Re: Seamless dungeon crawler effect

I think that by "seamless" he was just referring to the transitions between positions (a lot of dungeon crawlers just teleport you to the new position and it becomes horribly confusing as a lot of the time it looks like you didn't move), no need to be 100% smooth in that case. Sprites can make them ...

Re: Seamless dungeon crawler effect

Even if you only consider methods, everybody tends to implement things their own way, especially on these consoles where you need to manage different video resources (the two tilemaps and sprites) and pick a trade-off that suits your particular game best (contrast with newer stuff where you get a fr...

Re: Seamless dungeon crawler effect

I mean, when you see it's a few distinct graphics instead of there being obvious hints of some processing going on it becomes clear it's being assembled out of a few pre-existing graphics. I guess I jumped on it because I saw at least somebody attempt to use polygons thinking that Phantasy Star did ...

Re: Seamless dungeon crawler effect

They aren't rendered on the fly, they're prerendered images (more like predrawn) that get assembled together to make the dungeon. This is a very common thing among all dungeon crawlers. The exception to the rule that comes to my mind is Shin Megami Tensei on Mega CD, that one seems to be using Wolf3...

Re: Questions on writing a new Mega CD emulator

I forgot on which of the threads we had discussed this but whatever. I recall that we discussed that a handful of sectors from the lead-in are actually readable because they end up in the buffers — not enough to build an entire TOC, but a quirk nonetheless. Is it possible to try to peek at the buffe...

Re: Mega Man X

Nah it's not just you, it's barely dropping any health items. One issue I notice is that regularly the sound goes bonkers and ends up playing really loud noise (the music itself seems to continue just fine, looks like the PCM sound effects get broken). Usually it fixes itself after a few more sound ...

Re: Mega Mouse unused nibbles research

You missed the initial write in InitInput. Either way, I rewrote the whole thing as a state machine that changes what to do every frame and includes the reset sequence for both mouse and keyboard (・_・) (especially since the latter may actually need it if you press Reset in the middle of reading it, ...
