In regards to the Bandai Namco Flashback Blast which recently came out in various stores in the US, there was a controversy surrounding the version differences as well as the emulation issue. Firstly, when the product came out, both store versions had the home console versions of the games with one of the games being different depending on where you've bought that stuff from. What attracted more attention is that two reviewers had reviewed two different versions with one of them being given the product containing the arcade versions of the games as proven in the screenshots. Unfortunately, the one containing arcade versions cannot be found at all as all you get is the one containing home console versions.
John Hancock, the victim who was given the one containing the arcade versions as the review copy, was DECEIVED. It took him a few days for him to realize this after reviewing the product. It appears that ATGames had given reviewers like him the superior quality version that runs smoothly with customers getting an inferior performing one which obviously pissed them off. There are emulation issues plaguing the product that contains the home console versions. Not to mention that the screenshots DO NOT MATCH what's shown on the gaming screen whatsoever. A huge problem is that how shady the business practices are from ATGames as if the reviewers get given the superior performing version of the product while customers are given the inferior one so that it can be mis-reviewed or something. That caused John Hancock to be blamed or lose trust to people over that situation but thankfully, even he was PISSED and warned you NOT to buy that product at all costs.
There has been tons of Namco compilation games you can get but Bandai Namco Flashback Blast is the one you should avoid LIKE A PLAGUE! They surely contain the arcade versions although the 32-bit console versions have screen differences like the vertically-oriented games having shifted things over while retaining everything else from the arcade versions.
The worse thing was that ATGames blocked those who criticized their practices on Twitter as if the company thought the criticizers were trolling or something. If's there are professional criticisms thrown at you, all you have to do is analyze on what goes wrong and see if you can address the criticisms.
