Port of the game "Everlasting Summer" on SEGA mega drive. image
Development status
develop an engine (progress 100%)
port the prologue and release a ALPHA version
automate the conversion of original art into an 8-bit version in photoshop
port the all 7 day and release a DEMO version
write an 8-bit OST on the VGM-music algorithm
testing the game
The plot of the game
The main character ends up in the pioneer camp "Sovenok", where he must live for 7 days and solve the secret of the mysterious movement, or maybe find new acquaintances or even the love of his life.
Future plans
Release the game on https://itch.io/
Assemble a physical cartridge for the original SEGA
Concept and DevKit
The idea is to rewrite the original game on the 16-bit Sega MEGA drive platform.
The development uses the SGDK library - a free and open development kit for the Sega Mega Drive.
IDE - VSCode is used as a lightweight and quickly configurable integrated development environment.
Using the instructions, the environment was configured for simplified compilation and launch.
Project workspace
out/ # game binary (auto generate)
res/ # pictures, musics and fonts
src/ # code folder
boot/ # autogenerate folder for run game and set Game name on emulator
Game.h # include SGDK Libs and res/ folder for project
main.c # code for game
Structs.h # includes information from the res/folder for initializing the type of variables
compile.bat # VSCode cmd script for compile project
Problems and utilities fixes
The SDK does not support Cyrillic. There have been attempts to use a common font file from the res folder, but the method is not suitable for other functions, because it uses an array of bytes instead of a string.
solution: use a single font file from the res folder, replace all English letters with Russian letters. restriction: Russian alphabet consists of 33 letters, and English of 26. 6 ASCII characters of the code will have to be sacrificed for Russian letters. Moreover, the letters "Ъ", "Ы", "Ь" do not need to be written twice - a small letter is enough.

Convert original art
SEGA mega drive uses two screen resolution settings depending on the type of console:
Two main machine types:
NTSC machines
"Sega Genesis", 60Hz machines, primarily found in the US
Resolutions
H40 mode - 320x224 px (40x28 tiles). More common resolution mode
H32 mode - 256x224 px (32x28 tiles). Less common resolution mode
SGDK games are NTSC use
PAL machines
"Sega Mega Drive", 50Hz machines, everywhere else
Resolution
H40 mode - 320x240 px (40x30 tiles). More common resolution mode
H32 mode - 256x240 (32x30 tiles). Less common resolution mode
In this project use H40 mode 320x224 px.
All images use 8 bit channel of indexed color.
In Adobe Photoshop used Local(adaptive) pallitre with 32 color and transparency.
The local(adaptive) pallitre used points color for best mixed color on little resolution.
