Re: Street Fighter Alpha Mockup

On a fighting game both characters are the main and only focus, so half of VRAM sounds good to me; obviously it depends on game’s objectives/priorities. When you say 2x2x7KB, I believe you are referring to uploading half character per frame; that would be the extreme case, the “definitive fighting g...

Re: Street Fighter Alpha Mockup

I can’t download the ROM so I can’t tell how exactly you did thinks but if I have to do something similar my approach will be clear: During vblank around 7.4KB per frame can be upload to the VDP, so I will reserve a 2x 7KB on VRAM for each character and upload on every frame next character animation...

Re: Music for Sega homebrew games

I’m not sure a typical homebrew developer can pay 300 euros per song. I suppose is a matter of reevaluating the project, and decide when is ready to go ahead with music. Do you think a usual artist is willing to listen to criticism and modify its own music to suit better the project? And not the son...

Re: Music for Sega homebrew games

As a game programmer the main problem is that a concrete game needs specific tone or themed music. It will be much better to offer a site where both sides can meet and discuss together. Even be involved in the project and share gains,once the tile is launched.

Re: Hyrule in Megadrive/Genesis

Oh! I see what Chilly Willy meant: Earth has too much light from the Sun. Well, you can say that for Mercury, Earth and Mars too, on all of them looking directly at the sun hurts, at different intensities, but the idea is the same. Really the only difference between Earth and Mars is on the last, Su...

Re: Metal Blast 2277 - Sega Genesis / Mega Drive

Well done. Checking what Chinese have to offer is always a good idea. As is today, for example.

As they say "Follow yesterday light to find today's blast"... I'm pretty sure someone in the Universe says that...

Re: Sprite half in front of PLAN_A and the other half behind.

The whole effect can be done even better using only one plane: - Launching bombs characters are low priority - Using only plan B with low priority, except for - The tiles which are in front of the bomb launchers - Set black as the background color, and the same color number as index 0 on that palett...

Re: New device letters

Why it seems ugly if it's a byte value? Well, perhaps because it's meant to be read?
In lowercase seems just you forget to push shift. Also some parsers could ignore to upper/lower-case.

But you are the father of the creature after all, do what you think is right.

Re: New device letters

Sik, I think there are two approaches here: a) Every distinct device has its own letter. In that case lowercase is confusing. b) For sake of simplicity let’s group similar devices into groups, same letter if possible, or if there are small differences using letters that are more coincidental. Which ...

Re: SRAM read / write

How code (and if applies data) is structured depends on optimization flags, mostly related to cache hit and miss, there is no way to guarantee anything.

Re: SRAM read / write

Another solution is to create a new section and place those functions in this new section. Or reuse other previously created section. The only thing to look after is how sections are ordered. There is no relationship between sections and files, or n<->m relationship if you want. All this is specific...

Re: New device letters

Concerning the 8 button saturn pad on megadrive, I think the key factor is how data is served; if it follows the exact same pattern as 6 button megadrive pad, just two more bits for L and R (or however are labeled on saturn) I think it should add the character “8”. So the string for a game compatibl...

Re: New device letters

Perhaps it was used for internal testing on Sega headquarters just before gold production, to know with which type of input they should test the game. Just speculating.

And, yes it could be useful for and emulator for choosing the default device.

Buddy, with all the love in the word, your exact statement already has been said and answered; I don’t see the point in repeating it.
