Is there a list anywhere of MAME versions detailing when the major changes were made?
I'd like to find out the first version available when the 'video sliders' under the TAB key came into effect. I want a version of MAME that's better for older games but still has more video control.
Anyone?
Well you're implying that modern versions are somehow bad for older games, when the emulation quality should be better than ever..
but to answer your question, most people consider the video rewrite the tipping point, before that you could force more 'real' resolutions etc. The video rewrite is what effectively killed off AdvanceMAME etc. too because suddenly you got more complex support for dynamic resolutions, multiple screens with different refresh rates etc. rather than every driver assuming a single screen / resolution / refresh that would never change which broke an awful lot of their code.
the video rewrite is also the point at which things like the slider controls became possible in the form you see them today, because the new way of rendering / composing the image made things like that much easier. It's also the point at which you started to need a semi-decent (for the time..) video card instead of whatever trash you could find lying around which makes the post-video rewrite builds bad for really awful hardware.
so what you're asking for is basically something that doesn't exist, unless you're just believing all the nonsense people spout about the classic games somehow being better emulated in the ancient versions as a whole. Faster on low end hardware, yes, better emulated, no.
of course even more recently we've seen other significant changes to the video output, the whole HLSL thing (for which you do need a GOOD video card) gives fancy simulations of CRT monitor artefacts etc. and if you're wanting to use those to make things look pretty on an LCD screen you don't want to be running anything less than the very latest version, some important bug fixes went in regarding those filters (and there are almost certainly more to come..)
