- 3So if the alleged cheat had just bothered to mount his CRT sideways, he might have gotten away with it?Tommy– Tommy2018-11-05 18:15:39 +00:00Commented Nov 5, 2018 at 18:15
- 10Even with a sideways CRT there are still some differences in how MAME works compared to real hardware. In real hardware, the electron beam reads memory as it goes, so changes made to the display memory might appear immediately or delayed by a frame, depending on where the electron beam happened to be when the change was made. In MAME, a 'snapshot' of the display memory is made at a particular instant, and the electron beam draws from the snapshot. This leads to screen updates appearing in much larger 'chunks'.Ken Gober– Ken Gober2018-11-05 22:59:54 +00:00Commented Nov 5, 2018 at 22:59
- 7@Tommy Using MAME itself isn't exactly equivalent to cheating persay, but it's certainly suspicious for someone attempting a WR, especially if they claim it acts like the original, and should be inspected. IIRC the only reason it was even called cheating, is that the rules of the record, was that it be performed on original hardware. MAME prides itself on accuracy, so unless intentionally modified, any differences should be fixed where possible.Ryan Leach– Ryan Leach2018-11-05 23:16:22 +00:00Commented Nov 5, 2018 at 23:16
- 9There were two cheating issues. First he said that it was real hardware, either by mistake or deliberate, which invalidates the score and casts doubt on all his other ones. Second with MAME it is possible to use save states to cheat and then play back a fake run for the video, so even if MAME were verifiably identical to the real hardware no MAME run that wasn't witnessed live could be trusted.user– user2018-11-07 09:45:12 +00:00Commented Nov 7, 2018 at 9:45

print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. ms-dos), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
