We like to add beginner articles to our wiki, and invite experts to do the same. But what's a bridge too far for a beginner looks like a piece o' cake for an experienced MSX developer. Hence, such simple subjects simply don't pop up in the minds of those who like to help and write. So, we'd like to invite beginners to suggest where you're stuck. We'll help by creating (generic) wiki articles for just that topic!
Ask what you want, though keep it realistic and practical. We won't create your game. But if you want to know how to create a sprite, how to move a sprite, how to build up the screen.. for those smaller questions, a generic article is ideal. Also, don't ask things that take a talented artists a four year college education to understand. So, questions like "how do I create a complete set of background music for my game" or: "how do I draw an RPG" are simply too large to make sense. Well.. of course you could ask, but the chances of getting an article that makes sense in return are pretty slim..
