      I believe the 'Metal Slug' series should be working in lr-mame2003. Have you verified that the ROMs are indeed from the 0.78 ROM set? I have no idea about 'Blitz', but I just looked it up and I would be surprised if it played on the Pi at all with how graphically intense it appears. 'Killer Instinct' definitely falls into this category and can only be made to play at a few frames per second. 'Rampage' will not run on lr-mame2003, but is possible with lr-mame2010 and after, as well as the AdvanceMAME options.

        While I double check the rom verification, is lr-mame2010 available on the pi 3 as a worthwhile option?

          lr-mame2010 is available in the "optional" packages of the RetroPie-Setup script. It's worthwhile as a solution to get the classics up and running that won't play in lr-mame2003. However, MAME gets more and more accurate with each passing version, which also means it runs slower and slower on low-end devices like the Pi. Anything past the 1980's and you're likely to start seeing slowdown.

            @mediamogul Thank you , that helps a lot with my question.

            So I check the rom in MAME and it says some are 2003 and some are earlier and are working (in the current MAME version ) but when I attempt to run them I get an error that the CHD ( which those shouldn't have ) or missing one or more required roms. That is coming from the most current MAME executable on my windows laptop.

              I don't believe there's a way to check the ROM version within MAME itself. The link I posted above details how to do it though. If it's barking at you about missing files, it's most likely from the wrong ROM set.

                As a side note, I am under the impression I need a BIOS for the Metal Slug games since they are Neo Geo but putting the standard Neo Geo bios in the mame 2003 folder with the roms does not change anything.

                  The BIOS file must also be from the same ROM set.

                    You can put the ROMs in the Arcade folder and then choose a lf-fbalpha as your default emulator for them. I'm not sure if that will give you what you want, but for Neo Geo, I only use lr-fbalpha.

                      If you're going to mix and match ROMs anyway, lr-fbalpha is indeed the better solution to NEO-GEO.

                        @mediamogul Well, I was trying to keep everything separate so I could visuall see the differences and compare. I am attempting to use clrmamepro but and having trouble so I have not released my rom results yet.

                            @mediamogul Haha awesome ! I am running it now but am getting an error on every rom and a red x so I must have something incorrect since I hate almost off of them working.

                              @mediamogul @obsidianspider Thank you both, I upvoted all comments. It turned out to be the neogeo.zip was not from the romset. I did not catch that before when i unpacked the .78 romset. Thank you again, this is an amazing community. I do not know how to get or give rep on here as I just signed up recently but let me know and I will pass it on to you.

                                  @mediamogul It's almost always user error isn't it?

                                    I never make assumptions. I always eliminate Gremlins, Poltergeist and a TRON-like race of cyber people living in my technology before I even look at user error.

                                      For Metal Slug I would recommend lr-fbAlpha from my own experience, but beware, it requires a different neogeo.zip. If you place all your MAME roms into the Arcade folder, they all show up under Arcade (both FB Alpha and MAME), which is very cool. Running MS 1+2+3+X on my Pi3, but without complicated shaders and Video Smooth on.

                                          True, but if you don't do something about them, they'll soon develop their own art, culture and religion, which inevitably leads to the worst possible scenario for any intelligent society; holiday-themed variety shows.
