CRACK, TRAIN, FIX, RELEASE
CHRIS HEILMANN (@CODEPO8), DEVIT, THESSALONIKI,15/05/2015
MAN, I WAS AWESOME!
(I GOT A BIT BETTER)
IT ALL STARTED WITH A FLOPPY…
I SUCKED AT PLAYING GAMES - AND IT WAS FRUSTRATING.
TCS ➜ RUN ➜ ENDLESS LIVES!
THOSE CRACKERS MUST BE SOMETHING REALLY SPECIAL!
OPEN SESAME!
FREEZE GAME ➜ EDIT SCREEN ➜ FIND LIVES COUNTER ADDRESS (F.E. $0410) ➜ HUNT MEMORY FOR CE 10 04 (DEC $0410) ➜ REPLACE WITH EA EA EA (NOP NOP NOP) ➜ ENDLESS LIVES!
LET’S GO
THE DOOR WAS OPEN, AND I TOOK ONE STEP AT A TIME AND KEPT EXPLORING!
ENHANCE!
• Level skipper • Weapons chooser • Toggle sprite collision • Learn Assembly language to
write trainer menu • Find space in memory for said
menu
RELEASE!
• Learn about packers to create smaller version
• Add intro to boast • Give to people
UPPING THE GAME!
• Removing copy protections • Level crunchers/packers • Fast loaders
THE HACKER NEWS OF OLD…
COMPETITION• First release • Smallest release • NTSC/PAL fix
STANDING OUT FROM THE COMPETITION
• Jewel versions • Bug fixing • Highscore Savers • Writing Docs
ELITE ACCESS TOOLING MADE THE DIFFERENCE
• Packers • Storage/Transfer tools • Cross-platform tools • Creation tools (Assemblers,
Pixel Editors, Sprite tools…) • BBS/FTP access
GOING LEGIT
• Writing tools • Writing Games • Coding Intros/Demos • Moving on…
ACCIDENTAL ARCHIVISM
OHAI CINEMAWARE…
ACCIDENTAL ARCHIVISM
• Floppies ➜ BBS ➜ FTP • Original storage media is
unreadable • Original companies gone • No official backups
THINGS I LEARNED
THINGS I LEARNED
• Nothing can hold you back when you are good at analysing and repeating
• Everything you see on screen came from somewhere - it is never set in stone
• It is much more fun to explore and tweak than to get something handed to you
THINGS I LEARNED
• Working in a limited/unknown environment is a wonderful challenge
• You don’t need to feel limited by the environment you target - you can use whatever you want to create for it
• The more people do this, the more best practices can be shared.

• MUCH BETTER TOOLING • EXPERIENCE • SHARED TRICKERY AND
KNOWLEDGE • LOVE FOR THE PLATFORM
HELLO, WEB
HELLO VIEW SOURCE
• A big part of my success on the web was using view source and reverse engineering
• We all did, don’t let people tell you otherwise
• The lack of distance between creation and consumption was really down my alley…
HELLO, TOOLS…
• Crawlers, Link checkers • HTML Validators • Web Development toolbars • HTTP proxies, sniffers • Venkman, Frontpage Express
JS Debugger…
VIEW SOURCE+5/[H]/100%/JEWEL
VIEW SOURCE+5/[H]/100%/JEWEL
• These days, developer tools have replaced view source
• We have incredible insight into what our code does in the browser
• Of course, not everybody is ready for this…
Open sesame!WELCOME TO CYBER SPACE, HELP THE CYBER POLICE!
THE BEST PART?
• Our tooling is free and open • A lot of it is across platforms
and gives remote access to other devices
• You can use the web, virtualisation and cloud based machines to test for all kind of issues
• We can share and fix issues collaboratively in real-time.
AUTOMATION AND OPTIMISATION
• Task runners • Package managers • Pre-, Post-Compilers and
Transpilers • Cross-platform conversion
tools
YOU ALREADY HAVE ELITE STATUS
• Releasing tooling publicly is the norm
• You could even say it is a competitive race much like the cracking scene was
• There is no shortage of hype
REDACT.JS (RELEASE APRIL 1ST)
AND WHILST WE GET EXCITED ABOUT IMPRESSING ONE ANOTHER WITH AMAZING TOOLS THAT ONLY LACK APPLICATION IN REAL PRODUCTS…
THE WEB IS LOSING QUALITY.
https://twitter.com/Caged/status/590602214021922818
THE AVERAGE WEBPAGE NOW IS 2MB WITH > 100 REQUESTS!
https://twitter.com/scottjehl/status/595827049136267266
DJUSTET PRICING IS WHAT I CALL THAT!
ROAMING ON OUR MOBILES CAN BE UP TO 12 GBP / 10MB…
WHICH MEANS, I PAY ABOUT 3.32 EURO TO LOAD A WEB PAGE!
MALA…
THIS IS NOT DEALER QUALITY SOFTWARE
WE’RE FOCUSING TOO MUCH ON TOOLING AND PUT TOO MANY MAGICAL SOLUTIONS IN PLACE…
WHEREAS WE SHOULD CONCENTRATE ON CREATING AMAZING END PRODUCTS.
TIME TO CREATE SOME JEWEL RELEASES FOR THE WEB!
• Work cross-platform and input independent
• Perform jank-free at a sensible frame rate • Are small and simple and enhance when
possible • Use device storage to deliver repeated
content fast • Work offline • All browsers get what they can sensibly
display • Load dependencies on demand • Offer only as much as needed
THE WEB IS THE MOST VERSATILE AND NON-ELITE PLATFORM.
GO AND MAKE YOUR MARK!
