The original graphics were upscaled using a combination of traditional non-AI image scaling and Real-ESRGAN-based tools. Some were manually repainted afterward. For selected graphics, including character faces, OpenAI image-generation tools were used to reconstruct higher-resolution detail based on the original low-resolution artwork. The same tools were also used to extend some backgrounds for widescreen. I reworked the results by hand to make them fit the original artwork. Development of this remaster began in 2009; Codex has been used as a coding assistant since version 1.1.
