Raiden continue...?

MrQuan · Post by **MrQuan** » Tue Oct 30, 2007 3:21 am

G'day,

I've played the MAME version of Raiden recently and have noticed that when I'm hit, my new ship just reappears straight away and I can pickup my dropped powerups and continue. However, I own a Raiden PCB for one of my arcade machines, and when I'm hit, the screen does that green tile thingy and there are no powerups when I'm put back in the game. So instead of just continuing on, I'm interrupted by that tile animation and put back without powerups. I can put a video of it on youtube if that helps?

Has anyone seen this behaviour with Raiden? Have I got a different revision of the game? ...and can I somehow make my PCB like MAME? (e.g. burn the EPROMs or something). In any case, I'm fairly certain it's not a dip-switch issue.

Hopefully a resident expert here can point me in the right direction.

Many thanks,
MrQuan

Try the other romsets for Raiden. The Taiwanese set should default to checkpoints, like your board does. So, it should just be a ROM swap to make your board behave like MAME.

Coolio! Does that mean buying a heap of Raiden ROMs from somewhere? If so, where would I find them? Or is it possible to re-write the ones on the PCB easily?

Thanks:)

I have a an original US release PCB (Fabtek) and it does not use checkpoint. I like it better that way; it does not slow the pace of the game.

It might be possible that this condition only occurs when you are fighting a Boss or very near to the end of a certain stage. Raiden and similar shooters that subscribe to the "play over this section" are generally more strategic than the shooters that allow immediate and continuous recovery to enable grabbing those lost power-up items.

Shienryu also does this, meaning where if you die early in a given sector you start it over after the shield screen introduces you.

There just different game play philosophies and dynamics involved.

I don't know how to tell if mine is legit or not, I guess it is because it has lots of custom Seibu chips on it.

EDIT: Here's a pic of my PCB:...

(Seibu Kaihatsu), 0x81 = USA version (Fabtek license), 0x82 = Taiwan version (Liang HWA Electronics license), 0x83 = Hong Kong version (Wah Yan Electronics license) and 0x84 = Korean version (IBL Corporation license). There are also strings for Spanish, Greece, Mexico, Middle & South America though it's not clear if they are used.

Is there any easier way to find out what region it is? I don't have a ROM reader/writer thingy.[/list]

But it doesn't.

It's legit.

Take a picture of the title screen i.e. this one:

Then we might see what region you have.

Here's a couple of photos:...

Does that show you what you need to see?

Thanks

Actually it shows no licensee string at all so I would guess that
this is the Japanese version but this version in MAME does not have
checkpoints.

May I ask where you are located MrQuan ? And could you take a picture
of the PCB so we can see the chip labels or just write them down ?

Yeah, I'm in Australia. A lot of our PCBs in the local market are Japanese or Asian I guess. However, I ordered this Raiden PCB from the US because I couldn't find one here easily.

I'll take a high-res pic of it soon.

Thanks for your help

Ok, here's a high-res photo of my PCB.

I know it's hard to read, so let me know if you need me to read anything off the PCB for you.

What's written on the two EPROM's which are unreadable
because of the flash. The two horisontal ones at the bottom
of your image.

Not sure exaclty which ones you're after, so I took a close up:...

Still the same as mine, do you have any mates with an EPROM reader ?

Could be the Japanese version.

But then again it would said "For Japan Only" on the title screen.

I kind-of play better without checkpoints.

No, don't think so

but, it's probably about time I got an EPROM reader/writer myself, it was bound to happen with my arcade PCB collection anyways

Apparently there are decent USB ones. Do you know of any particularly good ones I should check out?

Yeah me too! It's really hard to come back half way through a difficult level with only the weak bullet fire, but I guess it's more incentive not to get hit?

I really want to get rid of the checkpoint system in mine.

On the JP version of Raiden Project for the PSX when you play Raiden they're checkpoints.

On the US version you can turn them off.

I wish there was a setting on the PCB for this, but there isn't

I've checked the dip-switch settings and there's no software settings.

A 2-Player game obviously just continues (not checkpoint), so I tried a 2-player game and let P2 die... but the game is different, more power ups etc, so that wasn't really an option.

Hopefully I can find a decent EPROM reader/writer - anyone know one??

I've just contacted a guy in the local arcade community, he repairs them etc so he should have all the EPROM kit. Hopefully he can help me out!
