Where to (legally) acquire content to play on RetroPie

themazingness

I just found out about this extensive list of NES homebrew games: https://retrostack.substack.com/p/the-top-500-nes-homebrews-vol-4?s=w

They added another one: Marzipans Beef Reverser!

Guys uhh ... wasn't there a decision a while back to make this into a wiki? Just submit new games to the wiki. Can this thread be locked?

themazingness

@BenMcLean Honestly, that was more work than I really cared for. I just wish this was on a forum you could do a decent search in. If they want to lock it I respect that (kinda have to anyway when that occurs). But until then this thread is stickied and open. Might as well use it.

If you look at the wiki, it doesn't remotely have the content we've discussed here. I think what we need is a place we can do a simple post to that can be searched. Wikis are great if you have a community of contributors with spare time. But they aren't great for a handful of enthusiasts sharing news about legal rom sources. Wikis are WAY too much work to be sustainable, and they aren't conducive to sharing the latest information. They're better for topics that don't require constant updates.

themazingness

Maybe we need to discuss something simpler? A Google spreadsheet maybe?

I also wonder if there isn't a better place for this. Here was great because you have the right mix of keeping things legal and still being enthusiastic about emulation. I really wish there was a larger, more active community interested in legal emulation. It feels like Retropie is getting less active. Wikia doesn't feel like the right community even if its tools were better suited.

The original The Curse of Monkey Island is one of the games given to members of Amazon Prime this month. It is setup to run in ScummVM.

Incidentally, this is one of the reasons why a wiki page isn't great. This is only true for this month. I've got an idea I'm mulling over for a searchable, updateable replacement for this thread.

@Auster Could I get a little guidance on 1943? Best I can tell it unpacks to 600+ unhelpfully named files.

elco2

@elco2 well I tried Ghost and Goblins, The data is more obvious, but still unclear how it relates to mame format. Here are the files that came out (with many more 0's on the front but I cut that off:
00.dat 155.95kb
01.mam 118b
02.mam 142b
03.pfb 331b
04.3ds 26b
05.dat 161.11kb
06.3ds 26b
07.scn 665b

@elco2

You can use mame standalone (latest version) to check which files it uses from a romset.
There are a few Ghost and Goblin versions :
gng (Ghosts'n Goblins (World? set 1)
gnga (Ghosts'n Goblins (World? set 2)
gngbl (Ghosts'n Goblins (bootleg with Cross)
gngblita (Ghosts'n Goblins (Italian bootleg, harder)
gngc (Ghosts'n Goblins (World? set 3)
gngprot (Ghosts'n Goblins (prototype)
gngt (Ghosts'n Goblins (US)

You can check the romsets of each version with this command (if you installed mame from the exp packages) (use gng or something else) :

/opt/retropie/emulators/mame/mame -listroms gng

It will display the filenames,sizes and sha1sums.
So if you have a sha1sum that matches, but your filename is different, then you can just rename your file to that specific name, listed by mame.
When you have gathered all the files then you can repack these files to a working zip.

Your files don't come close to the files in the mame romset.

Sometimes romfiles are joined and then you have to split them.
But seeing your files the sizes are not duplicated of 16k or something like that.

So I think you just have wrong files.

elco2

@Folly Thanks for the help. These files came out of re_dlc_stm_1556690.pak , which I think is the correct one for G&G. Perhaps the unpaker is not unpaking correctly anymore?

Folly

@elco2

Indeed that could be the problem.
Can't help you with that.

Perhaps someone else knows.

@Crush [ROM extracted from Capcom Belt Action Collection (Steam version).]removed.
The site is in Japanese, extraction is possible.
However, you need to create your own CPS2key.
Some ROMs have problems with CRCs and sound ROMs.

@mochimochi Please don't post links to ROMs, as per the forum rules.

@mitu NoROM site!!! convert script!!

Does global mean only English-speaking countries?
Are you a global administrator who cannot even view Japanese blogs through google translate?
I don't understand why you are deleting this when there is no legal problem and it doesn't conflict with the forum rules.

Has anyone tried running the ROMs from the Neogeo Pocket titles available on Steam in an emulator? I tried the Steam versions directly and the input lag was horrible. I'm fairly sure the originals weren't like this, curious if it's just a lousy emulator being used.

Auster

@SeeNoWeevil I didn't test those games yet, but usually, official emulator wrappers are either poorly optimized/configured, or outdated, or both. You'll probably have better results running them from an emulator of your choice. Btw, iirc, all the files you need to emulate them, BIOS included, can be found in the files of this NeoGeo Pocket bundle.

themazingness

@SeeNoWeevil I haven't noticed any input lag using an SN30 Pro or a Dualshock 4. I've played on my Android phone in RetroArch and an Intel based PC in Retroarch and the wrapper by Code Mystics.

I might have experienced it with Fatal Fury. I did find it difficult to pull off S moves, so maybe there? I just assumed it was my lack of skills since the rest worked fine, but I don't have experience on the actual hardware so I'd be ignorant of any discrepancies.
