Resource Budgets for Nethercore ZX
Console Limits
| Resource | Hard Limit | Typical | Warning |
|---|---|---|---|
| ROM Total | 16 MB | 8-12 MB | > 12 MB |
| WASM Code | 4 MB | 0.5-2 MB | > 2 MB |
| Data Pack | 12 MB | 4-10 MB | > 10 MB |
| RAM | 4 MB | 1-3 MB | > 3 MB |
| VRAM | 4 MB | 2-4 MB | > 3.5 MB |
| State Snapshot | - | 50-150 KB | > 200 KB |
Data Pack Budget
Typical allocation (12 MB max):
| Asset Type | Percentage | Budget |
|---|---|---|
| Textures | 40-60% | 4.8-7.2 MB |
| Meshes | 20-30% | 2.4-3.6 MB |
| Audio | 10-20% | 1.2-2.4 MB |
| Animations | 5-15% | 0.6-1.8 MB |
State Snapshot Sizing
For rollback netcode:
| Size | Frame Budget | Status |
|---|---|---|
| < 50 KB | < 1ms | Excellent |
| 50-100 KB | 1-2ms | Good |
| 100-200 KB | 2-4ms | Acceptable |
| > 200 KB | > 4ms | Optimize |
Quick Size Estimation
Texture: width × height × 0.5 bytes (BC7)
Mesh: vertices × 12-40 bytes (format dependent)
Audio: seconds × 44100 bytes (22050Hz mono)
XM Music: 50-200 KB per song
