Title: SGX shmup prototype
Post by: touko on October 28, 2013, 09:25:00 PM
Hi, i made a prototype of my new SGX game .. Sorry for graphics, they are stollen from metal slug and gradius .
This graphics were used quickly for RGC 2013, a retro gaming convention in france, but they allowed me to test my new PCE/SGX graphic libraries and more .
Musics were made for this game by RayXamBer,and title screen by crapahute .

very impressive to see all the scrolling and colors together! Could be amazing. I think a super polished, homebrew shmup for SGX would be rad as hell.

This brings up a couple interesting questions about the SGX. Using hsync tricks, could it be possible to emulate several overlapping background layers without the use of sprites? Also, with two video processors on tap, can the SGX use twice as many color palettes simultaneously?

TOUKO, I made comments on YouTube, but not here:

Yes, Hsync tricks can be used to overlap the same 2 BGs several times. The SGX has 2 VDCs, but only one VCE, which manages the palettes, so: same # of palettes as the PCE.
Cool demo, Touko!

Looks great. And Metal Slug graphics running on PCE hardware?, thats a dream come true! Very promising!

Yes, this is what i do,all parallaxes are tiles only, and the hud is also tiles . You cannot plays with background priority as Md/snes do, but you can easy do it manually, when you create the background layers .
Keep in mind that almost the graphics was done quickly, the final game should be better,and of course without ripped assets.
The main purpose of this alpha, is to test some new SGX/PCE routines, mainly for sprites (the old devkit method was not good for me) . And maybe BillyBoy will be the first SGX+scd²+AC game :D

Cool demo! Is there a technical reason that the background tiles repeat so quickly (memory limits or what not), or is it just because they're placeholders?

Don't worry it's just by laziness :wink:

I'm curious about the sounds.
Are the voices ADPCM, the music all CD (with some obvious chip sounds, such as the level intro and stuff)?
Are the sfx using Squirrel!?

No ,i use my own sound driver .. It's very easy and fast for classic sound fx, but not as advanced than squirrel .
As i use CDA for musics, i don't need advanced features of squirrel, because for now i am not yet able to make complex sounds.

LOL good luck , he's a megadrive intergrist and he is not really interested to evelop on other consoles, and probably because he also have not enough time .
