MK Arcade Kollection still has many issues not addressed.

[Goku]

For example, in MK1 during certain fatalities the characters are only suppose to scream for a limited time. In MKAK on all of the fatalities the characters scream 100% everytime even though the screams are suppose to be cut off. Same in MK2 and UMK3. Also in MK1, in the Courtyard there are 2 different Flawless Victory sound effects. MKAK only has one, the same everytime.

Some examples: Scream endings,

:47 is the fatality. Notice Subzero only screams until Kano rips the heart out, he stops after that.

Same video about :30 you can hear the Flawless Victory sound, notice is different than on the MKAK.

MKAK as we know it was started as MK HD Kollection. I dont think MKAK will ever really truly be like the old games because the base of this kollection was meant to be something different.

Those new sounds were meant for a new "update" to the games but because the filming changed too much, they canned it.

but it is also 2012, the 20th Anniversary of MK1, so i wouldnt be surprised if they released the MK1 HD Remix this year.
