Are DC ports of Naomi shmups arcade perfect?
Isn't the hardware really similar? What advantages are there to having the GD roms?
EDIT: I ask in part because I have every port of Shiki 2, but not the original. I'm thinking I'm not missing too much.

Birds in Border Down, and that's pretty much it.professor ganson wrote:What advantages are there to having the GD roms?

Some graphical effects in Trigger Heart are left out of the DC port.nem wrote:Birds in Border Down, and that's pretty much it.professor ganson wrote:What advantages are there to having the GD roms?

I'm not sure where you get the speed thing from. I generally haven't noticed slowdown in ports among truly similar systems (some systems have mostly superficial similarities, like Genesis/Megadrive and System 16/18). When there's a ROM to CD/GD conversion, load time obviously becomes a factor, but that's not usually an issue during gameplay.For any arcade system that's "similar" or "based off" a home system or vice versa, there are always port inaccuracies of some sort. And almost always, speed (based on too many variables) plays a part.

Same CPU, same video chip. The DC has half the video RAM and half the system RAM of NAOMI. Typically speaking, certain memory-hungry graphics will be left out, or textures scaled down when porting from NAOMI to DC.professor ganson wrote:Isn't the hardware really similar?
For a gamer on a budget, the DC works out pretty well as a "ghetto NAOMI". Speaking from the point of view of a guy with three kids and a mortgage, I have a DC in a cabinet and not a NAOMI for that very reason.

Naomi has double the ram. RAM management on Naomi games is configured slightly different. What this amounts to is that the arcade variants have no loading times as the next level is usually loaded prior to you finishing the current level.
Obviously on the DC, each level is loaded individually. Of course there are exceptions, some DC games load instantaneous, just depends on the type of game.
Something like Daytona USA on DC loads levels individually, if it was naomi there would be no noticeable loading times.
As far as graphics are concerned, its the same really.
Atomiswave is closer to DC spec, except it uses cards instead of discs. So the RAM problem is obsolete. I bet the sound is a bit crap though. I've never played a ATW game, even though I have an ATW cab

This industry has become 2 dimensional as it transcended into a 3D world.

Not necessarily slowdown (although that's generally not emulated perfectly either since it's so difficult to copy); the game speed in general is different. For any Naomi fighter port (CVS2 and MVC2 for 2 clear examples), if you time the length of a match on both versions (all other variables being equal), you'll get different numbers.Ex-Cyber wrote:I'm not sure where you get the speed thing from.

System 16 and 18's MD ports tend not to resemble the originals at all...

I haven't played the NAOMI version of Ikaruga either, but I'm 99% sure that the slowdown during boss explosions is intentional.J-Manic wrote:And here I always thought Ikaruga was "arcade perfect" (besides the slowdown during boss explosions?) on the DC. But I've never actually played the arcade, so what do I know (nothing).
Do you have examples, and have these been measured on different display types (particularly VGA vs. NTSC/PAL)? I don't especially doubt that what you're saying is true, but I'm curious about the phenomenon.Ganelon wrote:For any Naomi fighter port (CVS2 and MVC2 for 2 clear examples), if you time the length of a match on both versions (all other variables being equal), you'll get different numbers.
