Whenever possible I will be playing the game in its original cartridge form on the original console with original controllers. When necessary, I may use an emulator for the purposes of screenshots and videos. Here is the breakout:
For NES games, I will be playing on an original “toaster” style NES. I will use an NES Advantage controller when it suits the game; unfortunately I have arthritis in both my thumbs, and the original NES controllers are quite uncomfortable (and probably to blame for my arthritis in the first place). And yes, I will refrain from using the Turbo Buttons except for cases where the results are hilarious. Otherwise I will use the original, square NES controllers. For screenshot purposes, I use the FCEUX emulator (NES games are usually a) short and b) rely on passwords if they are long, so it is easy to catch up in the emulator to where I am on the actual cart). In some cases, due to rare games, I may just review the ROM.
For the SNES, I will be playing on the original, SNES-001 model, with official SNES controllers. If the games are involved and have on cartridge saves (Super Metroid, for instance) I will be using a Sabrent VD-GRBR to capture the video straight from the console to provide screenshots. If the game is short an easily played through on an emulator, I will likely screenshot straight from there. For N64, I feel that the emulators all look too clean, so I will be capturing all images with the Sabrent capture device straight from my original N64, complete with Jungle Green controller.
As for the reviews themselves, I will primarily be judging the game qualitatively. I will evaluate based on gameplay, controls, graphics (as much as possible for 25 year old games) and sound, and attempt to filter out any nostalgia effects. This will likely change as I do more reviews and better refine my process, but for now, this is what I’ve got.
