→Implemented support for loadable modules on small devices
| Line 105: | Line 105: | ||
Ideally, your code should be generic enough to be usable for all platforms. With two examples of the loader already in existence, this should quite doable. | Ideally, your code should be generic enough to be usable for all platforms.

Another factor to consider is that should you wish to build the loader for very memory-starved platforms such as the Nintendo DS, you will have to deal with an issue within the ScummVM architecture. Currently, the loadable modules are all initially loaded into memory. When a game is chosen by the user, the irrelevant modules are erased from memory. In order for the modules to fit into the limited Nintendo DS RAM, this method will have to change -- only one module should be loaded into memory at a time. | Another factor to consider is that should you wish to build the loader for very memory-starved platforms such as the Nintendo DS, you will have to deal with an issue within the ScummVM architecture.

We have some ideas on how to achieve that, talk to us. | ||
Once loadable modules work, there are potential tasks beyond this, which could be pursued if enough time is left. For example, on the NDS, even when only one engine is loaded, memory can still be too tight unless the core binary itself is reduced. Therefore, the NDS port disables MP3 support in certain engines, as well as certain other core features. But we would prefer to have a single binary which only loads modules as required. So, maybe one can turn the MP3 decoder (as well as other audio and video decoders and maybe further core components) into plugins, too, and only load them when required. Of course this opens up issues of its own, like now modules would have to be able to declare dependencies on each other. | |||
