May 19, 1999Darius Immanuel Guerrero creates his original AppSir website, and posts a welcome message to all visitors.
"Hello internet people! Welcome to my site! Boo Ya! Gonna make awesome games for the new millenium!"
June 2, 1999Meets someone unusual. Posts a beckoning skull GIF jokingly or out of suspicion.
"Huh. Weird person."
June 6, 1999Darius receives the source code for DERE SOURCE (then labeled DE**.EXE). Seems to trust the “weird person” enough now.
"Trying out my new friend's game for the first time. I think she made it herself. She's all that."
(See also the June 6, 1999 video footage posted on the AppSir YouTube channel.)
June 7, 1999Looks through DERE SOURCE, decides to take an internet poll to determine the missing two letters (DERE, DEXE, DEZE, or DESE).
"I got the game yesterday! There's a PC Version and then there's a version where it's for. I forgot which gaming machine. The game, It's... strange. AND TOO HARD TO PLAY! But the files contain a lot more pictures and characters than I see in the game itself. It's been abandoned by the creator (the one that gave it to me) and I promised I can finish it. The creator said yes!
The CD was given to me with a label DE**.EXE. The asterisks letters are smudged. So I guess we're going to have a poll on what to call the game and fill up the missing letters."
June 11, 1999More tests on the game.
"The game is rage-inducing. I like it. I will do more tests."
June 14, 1999Game copied and edited to create a cartoonish prototype. Notices that the two copies are connected somehow.
"I copied the game and edited it to make it look more cartoony. I like this cartoony prototype. It's strange though. It feels like they are connected. When I change the files in the bare version, the cartoony version changes as well."
June 16, 1999Made a GIF of the cartoony platform character.
"Finally! I got to make a gif of the character. Why does he/she look sad?"
July 6, 1999Apparently got an error message on computer while working. The GIF shared with the following quote showed someone working on a computer until a blue screen flashed on with the message: “This program has performed an illegal operation”.
"This picture represents what happened to me today."
August 21, 1999Darius’ birthday, some musings and discoveries about .exe files.
"It's my birthday! Rewatched The Lost World Jurassic Park with my friends. Also, I found out I didn't have to call my project with a '.exe game' because .exe is a file type. but I think it rolls of the tongue better. It also sounds so high-tech! Too bad I didn't get to finish my project De** .exe (missing letters are to be determined in the poll below)."
August 30, 1999Making progress on the platforming character. Considers making him a knight.
"I did made the character less sad, I think. I copied how it looks in the first iteration. Just the eyes left. Need to work on it more. Maybe turn him or her into a knight or something. Hope I can release this someday. You can still vote for the title in the poll at the bottom of the site!"
September 15, 1999Poll concludes, with “DERE” winning. Decides the sequel will be “DERE EVIL.EXE” because he likes the title of another game.
"I think Dere .Exe is a good name. And the sequel shall be Dere Evil .exe. I just finished playing Resident Evil 2 and I think this game's title can remind me of the good times. Hope I can launch this game soon."
September 28, 1999Sees strange glitches on computer, thinks he may have been hacked. Will take a break from working on his game.
"I've been getting some weird errors. I think I may have been hacked. I'm going to have to stop working on my game for a while. Maybe until I get a computer with Windows ME."
October 10, 1999Discovers the existence of an Atari version of DERE SOURCE, though the cover suggests the game's title to be DEMO.ATR. At the bottom of this cover is "Program & Audiovisual [copyright] 1980 Rotschstein." Suspects an NES version exists as well.
"I just saw an Atari cover and I think there's a NES version out there..."
