Hi all,

I use that wonderful SDL Mame (0.133) together with that beautiful Mameplus (1.4.7). My workstation is an Ubuntu 9.04.

Some time ago, I asked to Emuman (Mameplus author) how to play in Mameplus using IPS options. I've been told it is a SDL Mame matter, since if I'd use MameUI32, I'll be able to get these options.

My question is, would it be possible to compile SDL Mame with IPS support ?

IPS options for what exactly? For cheating in MAME you should install Pugsy's cheat pack.

From the IPS documentation:
Code:
MAME Plus! IPS Collection
Impossible! Perfect! Superior!
MAME Plus! IPS Collection, Make your gaming life I.P.S.!

ROM hacking is the process of modifying a video game ROM image
to alter the game's graphics, dialogue, levels, gameplay, or 
other gameplay elements. This is usually done by technically-
inclined video game fans to breathe new life into a cherished 
old game. Once a hack is completed, it is released by making a 
patch that can be applied to the unmodified ROM. [wikipedia]

We collect, organize and categorize these hacks, and put them 
into MAME Plus! IPS Collection. Featuring:
- No extra ROMs, dynamic loading of patches
- Continuous updating of a complete collection of hacks
- Detailed documentation including description and screenshots
- Customizable combination of hacks


So, no.. I can't see that being added to any official SDLMAME build simply due to it's content. An front-end might be able to perform such patches before runtime - but I know of none that do it currently besides Mameplus.

It is more advanced than a "simple" chat. It offers many more options.

Well, don't think it is a frontend matter; it it was the case, I would be to use IPS options when using MameplusGui.

What about the IPS content? Are you referring to legal issues? If you are: how many authorizations have been asked when dumping roms? Mame emulation is already in a grey area, hacking roms wouldn't be a so big issue.

Dude, MAME is about accurately preserving the contents of games. Hacking arcade games will receive no support here, because it results in people burning ROMs containing these translated / hacked / whatever games, putting them in their PCBs, and then sometimes selling these boards as ultra-rare revisions.

This screws up the MAME Dumping Project, because suddenly it's no longer clear whether or not that ultra-rare English version of an arcade game showing up on eBay is legitimate or because of some ass with an IPS. This has happened before, see Neill Corlett's ghastly hack of some racing game.

I don't think you're going to get a lot of support here.

man, asking for ips support here is inappropriate. sdlmame is a port of official mame and the ips thing is a pile of shit in mame philosophy.

although in theory, a front-end could do a temporary patch to bring similar functionality to official mame/sdlmame, it is still very ugly. so what you should ask is an sdl port of mameplus, which does not exist. if you really want to, you can launch mameplus with wine in mamepgui.

"Kingdom Grand Prix" is a shmup actually smile

And yes, frontends could pretty easily do the patching and pass a temp directory to the underlying (SDL)MAME.

That said, have you verified that the official cheat file does not contain the functionality you want? There are codes that do far more than simple cheating in there.

Really? Like fan translations? I never pay too much attention to the cheats, although it's nice to know people like stephh...

fan translations usually belongs to console hacks. from what I saw a couple of years ago (when I was helping with Misfitmame updates), mameplus ips files usually unlock boss characters or change moves... something definitely close to Pugsy's cheats

right, but in theory it could be done to an arcade game....

But if what you say is true, then Pugsy and company should be targeting duplication of the IPS patches in Cheat form (to kill IPS wrt MAME). CHEAT-Targets or something.
